16-BIT CMOS MICROCOMPUTER
PRELIMINARY
Notice: This is not a final specification.
Some parametric limits are subject to change.
PROCESSOR MODE
Only the microprocessor mode can be selected.

in the
microprocessor mode.
Figure 10 shows external memory area for the microprocessor mode.
Access to the external memory is affected by the BYTE pin, the wait
bit (bit 2 of the processor mode register 0 at address 5E
16
), and the
wait selection bit (bit 0 of the processor mode register 1 at address
5F
16
) .
___
BYTE pin
When accessing the external memory, the level of the BYTE pin is
used to determine whether to use the data bus as 8-bit width or 16-
bit width.
The data bus has a width of 8 bits when level of the BYTE pin is “H”,
and pins P2

are the data I/O pins.
The data bus has a width of 16 bits when the level of the BYTE pin is
“L”, and pins P2

When accessing the internal memory, the data bus always has a
width of 16 bits regardless of the BYTE pin level.
