FibreXtreme HW Reference for FPDP Cards
NOTE 2
: /TDIR, PIO1_OUT, PI02_OUT, and /RNRDY are decoded from the Serial
FPDP data stream by the decoder logic and are latched based on the last value received by
the data stream. These signals do not propagate through the Receive FIFO within the
SL100/SL240 CMC card and thus cannot be directly associated with the corresponding
data. Their use is not affected by the state of the Disable Receiver bit in the Link Control
register. Thus, /TDIR, PIO1_OUT, PIO2_OUT, and /RNRDY are received from the link
regardless of if the reception of link data is enabled.
