Data Bus Width
Data Bus Width
NOTES :
When BYTE Pin Input = H
When the data bus is 16 bits wide, the read and write signals can be chosen to be a combination of RD, BHE
and WR or a combination of RD, WRL and WRH by using the PM02 bit in the PM0 register. When the data
bus is 8 bits wide, use a combination of RD, WR and BHE.
Table 8.3 shows the Operation of RD, WRL, and WRH Signals. Table 8.4 shows the Operation of RD, WRL,
and BHE Signals.
The ALE signal latches the address when accessing the multiplex bus space. Latch the address when the ALE
signal falls.
1. If the entire CS space is assigned a multiplexed bus, these pins function as I/O ports.
