<description>The CONT (continuous) bit determines how the internal counter behaves when it reaches zero. If the CONT bit is 1, the counter runs continuously until it is stopped by the STOP bit. If CONT is 0, the counter stops after it reaches zero. When the counter reaches zero, it reloads with the value stored in the period registers, regardless of the CONT bit.</description>

<field>
<name>START</name>
<description>Writing a 1 to the START bit starts the internal counter running (counting down). The START bit is an event bit that enables the counter when a write operation is performed. If the timer is stopped, writing a 1 to the START bit causes the timer to restart counting from the number currently stored in its counter. If the timer is already running, writing a 1 to START has no effect. Writing 0 to the START bit has no effect.</description>

<description>Writing a 1 to the STOP bit stops the internal counter. The STOP bit is an event bit that causes the counter to stop when a write operation is performed. If the timer is already stopped, writing a 1 to STOP has no effect. Writing a 0 to the stop bit has no effect. If the timer hardware is configured with Start/Stop control bits off, writing the STOP bit has no effect.</description>

<description>The period_n registers together store the timeout period value when a write operation to one of the period_n register or the internal counter reaches 0. The timer's actual period is one cycle greater than the value stored in the period_n registers because the counter assumes the value zero for one clock cycle. Writing to one of the period_n registers stops the internal counter, except when the hardware is configured with Start/Stop control bits off. If Start/Stop control bits is off, writing either register does not stop the counter. When the hardware is configured with Writeable period disabled, writing to one of the period_n registers causes the counter to reset to the fixed Timeout Period specified at system generation time.</description>

<description>A master peripheral may request a coherent snapshot of the current internal counter by performing a write operation (write-data ignored) to one of the snap_n registers. When a write occurs, the value of the counter is copied to snap_n registers. The snapshot occurs whether or not the counter is running. Requesting a snapshot does not change the internal counter's operation.</description>

<name>DATA</name>
<displayName>Data</displayName>
<description>Embedded software accesses the read and write FIFOs via the data register. A read from the data register returns the first character from the FIFO (if one is available) in the DATA field. Reading also returns information about the number of characters remaining in the FIFO in the RAVAIL field. A write to the data register stores the value of the DATA field in the write FIFO. If the write FIFO is full, the character is lost.</description>

<fields>
<field><name>data</name>
<description>The value to transfer to/from the JTAG core. When writing, the DATA field holds a character to be written to the write FIFO. When reading, the DATA field holds a character read from the read FIFO.</description>
<bitOffset>0x0</bitOffset>
<bitWidth>8</bitWidth>
<access>read-write</access>
</field>
<field><name>rvalid</name>
<description>Indicates whether the DATA field is valid. If RVALID=1, the DATA field is valid, otherwise DATA is undefined.</description>

<name>CONTROL</name>
<displayName>Control</displayName>
<description>Embedded software controls the JTAG UART core's interrupt generation and reads status information via the control register. A read from the control register returns the status of the read and write FIFOs. Writes to the register can be used to enable/disable interrupts, or clear the AC bit.</description>

/* -----------------------------------------------------------------------
Round-robin/fixed arbitration implementation.
Q: how do you find the least-significant set-bit in an n-bit binary number, X?
A: M = X & (~X + 1)
Example: X = 101000100
101000100 &
010111011 + 1 =
101000100 &
010111100 =
-----------
000000100
The method can be generalized to find the first set-bit
at a bit index no lower than bit-index N, simply by adding
2**N rather than 1.
Q: how does this relate to round-robin arbitration?
A:
Let X be the concatenation of all request signals.
Let the number to be added to X (hereafter called the
top_priority) initialize to 1, and be assigned from the
concatenation of the previous saved-grant, left-rotated
by one position, each time arbitration occurs. The
concatenation of grants is then M.
Problem: consider this case:
top_priority = 010000
request = 001001
~request + top_priority = 000110
next_grant = 000000 <- no one is granted!
There was no "set bit at a bit index no lower than bit-index 4", so
the result was 0.
We need to propagate the carry out from (~request + top_priority) to the LSB, so
that the sum becomes 000111, and next_grant is 000001. This operation could be
called a "circular add".
A bit of experimentation on the circular add reveals a significant amount of
delay in exiting and re-entering the carry chain - this will vary with device
family. Quartus also reports a combinational loop warning. Finally,
Modelsim 6.3g has trouble with the expression, evaluating it to 'X'. But
Modelsim _doesn't_ report a combinational loop!)
An alternate solution: concatenate the request vector with itself, and OR
corresponding bits from the top and bottom halves to determine next_grant.
Example:
top_priority = 010000
{request, request} = 001001 001001
{~request, ~request} + top_priority = 110111 000110
result of & operation = 000001 000000
next_grant = 000001
Notice that if request = 0, the sum operation will overflow, but we can ignore
this; the next_grant result is 0 (no one granted), as you might expect.
In the implementation, the last-granted value must be maintained as
a non-zero value - best probably simply not to update it when no requests
occur.

// def: Burst Compression. In a merlin network, a compressed burst is one
// which is transmitted in a single beat. Example: read burst. In
// constrast, an uncompressed burst (example: write burst) is transmitted in
// one beat per writedata item.
//
// For compressed bursts which require response packets, burst
// uncompression is required. Concrete example: a read burst of size 8
// occupies one response-fifo position. When that fifo position reaches the
// front of the FIFO, the slave starts providing the required 8 readdatavalid
// pulses. The 8 return response beats must be provided in a single packet,
// with incrementing address and decrementing byte_cnt fields. Upon receipt
// of the final readdata item of the burst, the response FIFO item is
// retired.
// Burst uncompression logic provides:
// a) 2-state FSM (idle, busy)
// reset to idle state
// transition to busy state for 2nd and subsequent rdv pulses
// - a single-cycle burst (aka non-burst read) causes no transition to
// busy state.
// b) response startofpacket/endofpacket logic. The response FIFO item
// will have sop asserted, and may have eop asserted. (In the case of
// multiple read bursts transmit in the command fabric in a single packet,
// the eop assertion will come in a later FIFO item.) To support packet
// conservation, and emit a well-formed packet on the response fabric,
// i) response fabric startofpacket is asserted only for the first resp.
// beat;
// ii) response fabric endofpacket is asserted only for the last resp.
// beat.
// c) response address field. The response address field contains an
// incrementing sequence, such that each readdata item is associated with
// its slave-map location. N.b. a) computing the address correctly requires
// knowledge of burstwrap behavior b) there may be no clients of the address
// field, which makes this field a good target for optimization. See
// burst_uncompress_address_counter below.
// d) response byte_cnt field. The response byte_cnt field contains a
// decrementing sequence, such that each beat of the response contains the
// count of bytes to follow. In the case of sub-bursts in a single packet,
// the byte_cnt field may decrement down to num_symbols, then back up to
// some value, multiple times in the packet.
