Chapter 15. Registers Page 15-101
If the RDY signals are synchronized to IFCLK, and obey the setup and hold times with respect
to this clock, the user can set SAS=0, which causes the RDY signals to pass through a single
flip-flop.
Bit 5 TCXRDY5 TC Expiration Replaces RDY5
To use the transaction count expiration signal as a ready input to a waveform, set this bit to 1.
Setting this bit will take the place of the pin RDY5 in the decision point of the waveform. The
default value of the bit is zero (in other words, the RDY5 from the pin prevails).
