P60/DQ0
P67/DQ7
I/O port P5
8-bit I/O port.
CMOS compatible input level.
CMOS 3-state output structure.
I/O direction register allows each pin to be individually
programmed as either input or output.
When enabling the bus interface function, CMOS or TTL
input level can be selected as its input.
5-bit I/O port.
CMOS compatible input level.
CMOS 3-state output structure.
I/O direction register allows each pin to be individually
programmed as either input or output.

I/O port P8
8-bit I/O port.
CMOS compatible input level.
CMOS 3-state output structure.
I/O direction register allows each pin to be individually pro-
grammed as either input or output.

Remarks
DMAOUT pin
If externally detecting the timing of DMA execution, use the signal from this pin. It is “H” level during DMA transferring. This signal is valid in the memory expansion
and microprocessor modes.
SYNCOUT pin
If externally detecting the timing of OP code fetch, use the signal from this pin. This signal is valid in the memory expansion and microprocessor modes.
