General-purpose I/O port
This function is valid in single-chip mode and when the
CLK output is disabled.
CLK output pin
This function is valid in a mode where the external bus
is enabled and the CLK output is enabled.
General-purpose I/O port
This function is always valid.
UART0 serial data input pin
During UART0 input operations, UART0 inputs may be
used at any time.
It is necessary to stop port output when UART0 inputs,
except using port output deliberately.
General-purpose I/O port
This function is valid when the UART0 serial data
output is disabled.
UART0 serial data output pin
This function is valid when the UART0 serial data
output is enabled.
General-purpose I/O port
This function is valid when the UART0 clock output is
disabled.
UART0 clock I/O pin
This function is valid when the UART0 clock output is
enabled.
During UART0 input operations, UART0 inputs may be
used at any time.
It is necessary to stop port output when UART0 inputs,
except using port output deliberately.
General-purpose I/O port
This function is always valid.
UART1 serial data input pin
During UART1 input operations, UART1 inputs may be
used at any time.
It is necessary to stop port output when UART1 inputs,
except using port output deliberately.
General-purpose I/O port
This function is valid when the UART1 serial data
output is disabled.
UART1 serial data output pin
This function is valid when the UART1 serial data
output is enabled.
