Standard Read and Write Protocols
Read waveforms
•NRD waveform
In the following sections, the byte access type is not considered. Byte select lines (NBS0 to
NBS3) always have the same timing as the address bus (A). NWE represents either the NWE
signal 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.:
Figure 28-9. Standard Read Cycle
The NRD signal is characterized by a setup timing, a pulse width, and a hold timing.
1. NRDSETUP: the NRD setup time is defined as the setup of address before the NRD fall-
2. NRDPULSE: the NRD pulse length is the time between NRD falling edge and NRD rising
