General-purpose I/O ports
This function is valid in single-chip mode.
I/O pins for the lower 8 bits of the external address/
data bus
This function is valid in modes where the external bus
is enabled.
General-purpose I/O ports
This function is valid in single-chip mode.
I/O pins for the upper 8 bits of the external address/
data bus
This function is valid in modes where the external bus
is enabled.
Wake-up interrupt I/O pins
This function is valid in single-chip mode.
When external interrupts are enabled, external
interrupt inputs may be used at any time.
It is necessary to stop port output when external
interrupt inputs, except using port output deliberately.
General-purpose I/O ports
This function is valid either in single-chip mode or
when the external address output control register
specification is “port.”
External address bus output pins A16 to A19
This function is valid in modes where the external bus
is enabled and the upper address control register
specification is “address.”
General-purpose I/O ports
This function is always valid.
Reload timer 0 and 1 event input pins
During reload timer input operations, reload timer
inputs may be used at any time.
It is necessary to stop port output when reload timer
inputs, except using port output deliberately.
General-purpose I/O ports
This function is valid when the reload timer 0 and 1
output is disabled.
Reload timer 0 and 1 output pins
This function is valid when the reload timer 0 and 1
output is enabled.
