WAIT Polarity
The WAIT Polarity (WP) bit selects the asserted, or true, state of WAIT. When WP is set, WAIT is
an active-high signal (default). When WP is cleared, WAIT is an active-low signal.
Data Hold
For burst read operations, the Data Hold (DH) bit determines whether the data output remains valid
on D[15:0] for one or two clock cycles. When DH is set, output data is held for two clocks
(default). When DH is cleared, output data is held for one clock cycle. (See
processor’s data setup time and the flash memory’s clock-to-data output delay should be
considered in determining whether to hold output data for one or two clocks.
