Table 453: Retry Buffer Read/Write Debug Port (Offset 0x7D38)

Description
Data written to this address is written into the retry buffer
RAM at the retry buffer write address. Reads to this
address will return the data stored at the retry buffer read
address in the retry buffer RAM.

Table 455: TLP Error Counter Register (Offset 0x7D40)

Description
Write as 0, ignore when read.
Counts number of TLPs with bad sequence number
received since last read. Counter freezes at max value
and will be cleared to one if event occurs simultaneously
to read.
Counts number of bad TLPs received (includes bad
LCRC, bad length or bad sequence number) since last
read. Counter freezes at max value and will be cleared to
one if event occurs simultaneously to read.
