6.2.1
ABWCR is an 8-bit readable/writable register that selects 8-bit or 16-bit access for each area.
Bit
When ABWCR contains H'FF (selecting 8-bit access for all areas), the chip operates in 8-bit bus
mode: the upper data bus (D
bit is cleared to 0 in ABWCR, the chip operates in 16-bit bus mode with a 16-bit data bus (D
D
modes 2 and 4, ABWCR is initialized to H'00 by a reset and in hardware standby mode. It is not
initialized in software standby mode.
