interval between scheduling of training sequences on
the SPI5data path. If the DatamaxT field shows 0,
then the core never sends periodic training.

Tstat bus before the TxSPI module enters the
out-of-frame state. This signal can be safely set at any
time.

match clauses.
DIP2 is a parity algorithm where a 2-bit odd
parity is computed diagonally over status
words.
