2.2.4 Single Word Transfers
Single Word Transfers are used to support lower data rates than the maximum parallel data rate of
148.5 MByte/s. VALID has to be de-asserted after the parallel read cycle signaled by one RDCLK pulse.
Only one data word is transmitted.
In the timing diagram PARGEN is de-asserted and the application delivers the PARITY bit synchronously
to the data word.

* A dislock pulse generates an internal transmitter reset. Therefore both signals have to be at least
50us at high state before transmitter is operational.
Description
Setup time PDATA and PARITY to RDCLK rising edge
VALID active to rising RDCLK edge
VALID high state
LOCK# / RESET# high state before TX operational *
PDATA and PARITY hold time
RDCLK high state (without assertion of FLAGI)
Rising RDCLK edge to sampling window for VALID state
(VALID=0: continue single word mode,
VALID=1: enter BURST mode)
