P73
E
General-purpose I/O port
This port is available when the UART (ch.0) clock output is
disabled.
SCK0
UART (ch.0) clock output pin
This pin is available when the UART (ch.0) clock output is
enabled.
UART (ch.0) external clock input pin
This pin is available when the port is in input mode and the UART
(ch.0) specification is external clock mode.
49
P74
E
General-purpose I/O port
This port is always available.
SID0
UART (ch.0) serial data input pin
Since this input is used whenever the UART (ch.0) is in input
operation, the output by any other function must be suspended
unless the output is intentionally performed.
50
P75
E
General-purpose I/O port
This port is available when the UART (ch.0) serial data output is
disabled.
SOD0
UART (ch.0) serial data output pin
This pin is available when the UART (ch.0) serial data output is
enabled.
51, 52
P80, 81
D
General-purpose I/O port
This port is always available.
When these pins are open in input mode, through current may
leak in stop mode/reset mode, be sure to fix these pins to V
level to use these pins in input mode.

INT0, INT1
External interrupt request input pin
Since this input is used whenever external interrupts are
enabled, the output by any other function must be suspended
unless the output is intentionally performed.
When these pins are open in input mode, through current may
leak in stop mode/reset mode, be sure to fix these pins to V
level to use these pins in input mode.
