General-purpose I/O port
This function is valid when clock output from
UART0 is disabled.
Clock I/O pin of UART0
This function is valid when clock output from
UART0 is enabled.
Because this input is used as required when
UART0 is performing input operations, and it is
necessary to stop outputs by other functions
unless such outputs are made intentionally.
General-purpose I/O port
This function is always valid.
Serial data input pin of UART1 (SCI)
Because this input is used as required when
UART1 (SCI) is performing input operations, and it
is necessary to stop outputs by other functions
unless such outputs are made intentionally.
General-purpose I/O port
This function is valid when serial data output from
UART1 (SCI) is disabled.
Serial data output pin of UART1 (SCI)
This function is valid when serial data output from
UART1 (SCI) is enabled.
General-purpose I/O port
This function is valid when clock output from
UART1 (SCI) is disabled.
Clock I/O pin of UART1 (SCI)
This function is valid when clock output from
UART1 (SCI) is enabled.
Because this input is used as required when
UART1 (SCI) is performing input operations, and it
is necessary to stop outputs by other functions
unless such outputs are made intentionally.
General-purpose I/O port
This function is valid when waveform output from
8/16-bit PPG timer 0 is disabled.
Output pin of 8/16-bit PPG timer 0
This function is valid when waveform output from
8/16-bit PPG timer 0 is enabled.
