format
F
[DACK1] Output of DMAC external transfer
request acceptance (ch1). This function is valid
when the output of DMAC transfer request
acceptance is enabled.
[PE7] General-purpose I/O port. This function is
valid when the output of DMAC transfer request
acceptance or DACK1 output is disabled.
F
[SI0] UART0 data input
[TRG0] External trigger
input of PWM timer
[PF1] General-purpose I/O port.
F
[SO0] UART0 data output. This function is valid
when UART0 data output is enabled.
[TRG1] External trigger input of PWM timer. This
function is valid when PF1 and UART0 data output
is disabled.
[PF1] General-purpose I/O port. This function is
valid when UART0 data output is disabled.
F
[SC0] UART0 clock I/O. Clock output can be used
when UART0 clock output is enabled.
[OCPA3] PWM timer output. This function is valid
when PWM timer output is enabled.
[PF2] General-purpose I/O port. This function is
valid when UART0 clock output is disabled.
F
[SI1] UART1 data input
[TRG2] External trigger
input of PWM timer
[PF3] General-purpose I/O port.
Function
The input of each pin
is used from time to
time while input
operation is selected.
Therefore, it is needed
to stop output by other
functions except when
such output is
performed
intentionally.
