Selection Method and Pin Functions
The pin function is switched as shown below according to the operating mode,
bit PF3DDR, and bit LWROD in SYSCR.
The pin function is switched as shown below according to the combination of
the operating mode, and bits RMTS2 to RMTS0 *
to ABW2, BREQOPS, WAITPS, and PF2DDR.
Notes: 1. When DRAM space is designated for 8-bit access and PF
The pin function is switched as shown below according to the combination of
the operating mode, and bits BRLE and PF1DDR.

as the WAIT input, this pin can be used for WAIT input when all
areas selected as DRAM space are 8-bit space and normal space
other than DRAM space is 16-bit space.
