WAIT Polarity
The WAIT Polarity bit (WP), RCR.10 determines the asserted level (V
When WP is set, WAIT is asserted high (default). When WP is cleared, WAIT is asserted
low. WAIT changes state on valid clock edges during active bus cycles (CE# asserted,
OE# asserted, RST# deasserted).
WAIT Signal Function
The WAIT signal indicates data valid when the device is operating in synchronous mode
(RCR.15 =0). The WAIT signal is only “deasserted” when data is valid on the bus.
When the device is operating in synchronous non-array read mode, such as read
status, read ID, or read CFI. The WAIT signal is also “deasserted” when data is valid on
the bus.
WAIT behavior during synchronous non-array reads at the end of word line works
correctly only on the first data access.
When the device is operating in asynchronous page mode, asynchronous single word
read mode, and all write operations, WAIT is set to a deasserted state as determined
by RCR.10. See
