In the following sections, the byte access type is not considered. Byte select lines (NBS0 to
NBS3) always have the same timing as the A address bus. NWE represents either the NWE sig-
nal in byte select access type or one of the byte write lines (NWR0 to NWR3) in byte write
access type. NWR0 to NWR3 have the same timings and protocol as NWE. In the same way,
NCS represents one of the NCS[0..5] chip select lines.
The read cycle is shown on
The read cycle starts with the address setting on the memory address bus, i.e.:
The NRD signal is characterized by a setup timing, a pulse width and a hold timing.
1. NRD_SETUP: the NRD setup time is defined as the setup of address before the NRD
2. NRD_PULSE: the NRD pulse length is the time between NRD falling edge and NRD
3. NRD_HOLD: the NRD hold time is defined as the hold time of address after the NRD
