•NWE waveforms
Figure 15-10. READMODE = 0: Data Is Sampled by SMC Before the Rising Edge of NCS
The write protocol is similar to the read protocol. It is depicted in
write cycle starts with the address setting on the memory address bus.
The NWE signal is characterized by a setup timing, a pulse width and a hold timing.
The NWE waveforms apply to all byte-write lines in byte write access mode: NWR0 to NWR3.
The NCS signal waveforms in write operation are not the same that those applied in read opera-
tions, but are separately defined.
1. NWESETUP: the NWE setup time is defined as the setup of address and data before
2. NWEPULSE: the NWE pulse length is the time between NWE falling edge and NWE
3. NWEHOLD: the NWE hold time is defined as the hold time of address and data after
