External interrupt request input pin
This pin is used for input during corresponding interrupt is enabled,
and it is necessary to disable output for other functions from this pin
unless such output is made intentionally.
UART2 clock I/O pin
Clock output is available when UART2 clock output is enabled.
Can be configured as the I/O port when INT3 and SC2 are not used.
This function is available when UART2 clock output is disabled.
External transfer request input pins for DMA
These pins are used for input when external trigger is selected to
cause DMAC operation, and it is necessary to disable output for
other functions from these pins unless such output is made inten-
tionally.
Can be configured as I/O ports when DREQ0, DREQ1 are not
used.
External transfer request acknowledge output pin for DMAC (ch. 0)
This function is available when transfer request output for DMAC is
enabled.
Can be configured as the I/O port when DACK0 is not used.
This function is available when transfer request acknowledge out-
put for DMAC or DACK0 output is disabled.
External transfer request acknowledge output pin for DMAC (ch. 1)
This function is available when transfer request output for DMAC is
enabled.
Can be configured as the I/O port when DACK1 is not used.
This function is available when transfer request output for DMAC or
DACK1 output is disabled.
UART0 data input pin
This pin is used for input during UART0 is in input operation, and it
is necessary to disable output for other functions from this pin un-
less such output is made intentionally.
PWM timer external trigger input pin
This pin is used for input during PWM timer external trigger is in in-
put operation, and it is necessary to disable output for other func-
tions from this pin unless such output is made intentionally.
Can be configured as the I/O port when SI0 and TRG0 are not used.
