Circuit type
A High-speed clock oscillation pins (16.5 MHz)
H External interrupt request inputs 0 to 3
These inputs are always in use while the
corresponding external interrupts are enabled. Stop
port output in advance unless the resulting processing
is intentional.
This port can be used to release the standby status
because its input is enabled even during standby.
Can be used as a port when the pin is not used for
external interrupt request input.
H Used for both chip select outputs and external interrupt
request inputs 4 to 7
Can be used for external interrupt request input or as a
port when chip select output is disabled.
These inputs are always in use while the
corresponding external interrupts are enabled. Stop
port output in advance unless the resulting processing
is intentional.
This port can be used to release the standby status
because its input is enabled even during standby.
Can be used as a port when the pin is not used for
external interrupt request input and chip select output.
H External interrupt request inputs 8 to 13
These inputs are always in use while the
corresponding external interrupts are enabled. Stop
port output in advance unless the resulting processing
is intentional.
[AIN, BIN] Up/down timer input
[TRG] PPG external trigger input
These inputs are always in use while they are enabled.
Stop port output in advance unless the resulting
processing is intentional.
Can be used as a timer when the pin is not used for
external interrupt request input, up/down timer input,
and PPG external trigger input.
H External interrupt request input 14
This input is always in use while the corresponding
external interrupt is enabled. Stop port output in
advance unless the resulting processing is intentional.
[DEOP2] DMA external transfer end output
Effective when DMAC external transfer end output
specification is enabled.
Can be used as a port when the pin is not used for
external interrupt request input or DMA external
transfer end output.
