PSRAM WAIT Signal
The WAIT signal is used in synchronous mode to indicate to the host system periods of
invalid data. Periods of invalid data are caused by:
1. First access delays, or
2. End of Row condition for continuous or wrap-off burst settings.
For fixed length bursts with wrap on, WAIT remains deasserted when the End of Row is
reached and the burst will wrap around and continue without any delay. Therefore for
fixed length bursts with wrap on, WAIT is only asserted during First access delays.
For continuous or wrap-off burst length configuration, End of Row condition, WAIT will
transition from being de-asserted to being asserted within the time window defined by
tKOH and tWK. Depending on the implementation for a burst write, WAIT may be
asserted at the same time as the delay (condition A of Figure 29) or one clock cycle
later (condition B of Figure 29.) This inconsistency does not occur during burst read.
