– Null Pulse
– Write is Controlled by NWE (WRITE_MODE = 1):
Write Mode
Figure 27-14. Null Setup and Hold Values of NCS and NWE in Write Cycle
Programming null pulse is not permitted. Pulse must be at least set to 1. A null value leads to
unpredictable behavior.
The WRITE_MODE parameter in the MODE register of the corresponding chip select indicates
which signal controls the write operation.
Figure 27-15
put on the bus during the pulse and hold steps of the NWE signal. The internal data buffers are
turned out after the NWE_SETUP time, and until the end of the write cycle, regardless of the
programmed waveform on NCS.
