_________
When set to the 16-bit data bus, the PM02 bit in the PM0 register selects a combination of the RD, WR
and BHE signals or the RD, WRL and WRH signals to determine the read or write signal. When the DS3
to DS0 bits in the DS register are set to "0" (8-bit data bus), set the PM02 bit to "0" (RD/WR/BHE). If any
of the DS3 to DS0 bits are set to "1" (16-bit data bus) when accessing an 8-bit space, the combination of
_____
RD, WR and BHE is automatically selected regardless of the PM02 bit setting. Tables 7.3 and 7.4 list
each signal operations.
The RD, WR and BHE signals are combined for the read or write signal after reset.
When changing the combination to RD, WRL and WRH, set the PM02 bit before writing data to an
external memory.
When using the DRAMC to access the DRAM with the 16-bit bus, set the PM02 bit to "1" (RD/ WRL/
WRH).
