Circuit type
P UART0 clock I/O, Reload Timer 0 output
Acts as output for Reload Timer 0 when UART0 clock
output is disabled and Reload Timer 0 output is
enabled.
Can be used as port when UART0 clock output and
reload timer output are disabled.
P UART0 data output
Effective when UART0 data output specification is
enabled.
Can be used as a port when UART0 data output
specification is disabled.
P UART0 data input
This input is always in use while UART0 is performing
input processing. Stop port output in advance unless
the resulting processing is intentional.
Can be used as a port when the pin is not used for
UART0 data input.
F DMA external transfer request input
This pin is always in use when the pin is selected for a
DMA controller transfer source. Stop port output in
advance unless the resulting processing is intentional.
Can be used as a port when the pin is not used for
DMA transfer request input.
F DMA external transfer request acceptance output
Effective when external transfer request acceptance
output specification of the DMA controller is enabled.
Can be used as a port when external transfer request
acceptance output specification of the DMA controller
is disabled.
F DMA external transfer end output
Effective when external transfer end output
specification of the DMA controller is enabled.
F DMA external transfer request input
This pin is always in use when the pin is selected for a
DMA controller transfer source. Stop port output in
advance unless the resulting processing is intentional.
Can be used as a port when the pin is not used for
DMA transfer request input.
F DMA external transfer request acceptance output
Effective when external transfer request acceptance
output specification of the DMA controller is enabled.
Can be used as a port when external transfer request
acceptance output specification of the DMA controller
is disabled.
F DMA external transfer end output
Effective when external transfer end output
specification of the DMA controller is enabled.
