PROCESSOR MODE
Only the microprocessor mode can be selected.
___
Figure 9 shows the functions of pins P00/CS 0 — P47 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 5E16), and the
wait selection bit (bit 0 of the processor mode register 1 at address
5F16) .
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 P20/A0/D0 — P27/A7/D7 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 P20/A0/D0 — P27/A7/D7 and pins P10/A8/D8 — P17/A15/
D15 are the data I/O pins.
When accessing the internal memory, the data bus always has a
width of 16 bits regardless of the BYTE pin level.
Not used
Must be “10” (“10” after reset)
Wait bit
0 : Wait
1 : No wait
Software reset bit
Reset occurs when this bit is set to “1”
Interrupt priority detection time selection bit
0 0 : Internal clock
! 7 (cycle)
0 1 : Internal clock
! 4 (cycle)
1 0 : Internal clock
! 2 (cycle)
Must be “0”
