Function
UART2 clock I/O, Reload timer 2 output
When UART2 clock output is not allowed, reload timer 2 can be output by
P allowing it.
This pin is available as a port when neither UART2 clock output nor reload
timer output is allowed.
UART2 data output
P This function is activated when UART2 data output is allowed.
This pin is available as a port when UART2 clock output is not allowed.
UART2 data input
Since this input is used more or less continuously while UART2 is en-
P gaged in input operations, output by the port needs to be stopped except
when it is performed deliberately.
This pin is available as a port when UART2 data input is not in use.
UART1 clock I/O, Reload timer 1 output
When UART1 clock output is not allowed, reload timer 1 can be output by
P allowing it.
This pin is available as a port when neither UART1 clock output nor reload
timer output is allowed.
UART1 data output
P This function is activated when UART1 data output is allowed.
This pin is available as a port when UART1 clock output is not allowed.
UART1 data input
Since this input is used more or less continuously while UART1 is en-
P gaged in input operations, output by the port needs to be stopped except
when it is performed deliberately.
This pin is available as a port when UART1 data input is not in use.
UART0 clock I/O, Reload timer 0 output
When UART0 clock output is not allowed, reload timer 0 can be output by
P allowing it.
This pin is available as a port when neither UART0 clock output nor reload
timer output is allowed.
UART0 data output
P This function is activated when UART0 data output is allowed.
This pin is available as a port when UART0 clock output is not allowed.
UART0 data input
Since this input is used more or less continuously while UART0 is en-
P gaged in input operations, output by the port needs to be stopped except
when it is performed deliberately.
This pin is available as a port when UART0 data input is not in use.
DMA external transfer request input
Since this input is used more or less continuously when selected as a
F
DMAC transfer factor, output by the port needs to be stopped except when
it is performed deliberately.
This pin is available as a port when DMA external transfer request input is
not in use.
