Function
[SCK0] is clock I/O for UART0.
This function is valid when UART0 clock output is allowed
or when external clock input is used.
[PI2] is a general-purpose I/O port.
This function is valid when UART0 clock output is not
allowed or when external clock input is not used.
[SI1] is data input for UART1.
Since this input is always used when UART1 input is
operating, output using the port must be stopped beforehand
unless this operation is the intended operation.
[PI3] is a general-purpose I/O port.
[SO1] is data output from UART1.
This function is valid when UART1 data output is allowed.
[PI4] is a general-purpose I/O port.
This function is valid when UART1 data output is not
allowed.
[SCK1] is clock I/O for UART1.
This function is valid when UART1 clock output is allowed
or when external clock input is used.
[PI5] is a general-purpose I/O port.
This function is valid when UART1 clock output is not
allowed or when external clock input is not used.
[SI2] is data input for UART2.
Since this input is always used when UART2 input is
operating, output using the port must be stopped beforehand
unless this operation is the intended operation.
[PH0] is a general-purpose I/O port.
[SO2] is data output from UART2.
This function is valid when UART2 data output is allowed.
[PH1] is a general-purpose I/O port.
This function is valid when UART2 data output is not
allowed or when external shift clock input is used.
[SCK2] is clock I/O for UART2.
This function is valid when UART2 clock output is allowed
or when external clock input is used.
[PH2] is a general-purpose I/O port.
This function is valid when UART2 clock output is not
allowed or when external clock input is not used.
