P70
E
General-purpose I/O port
This port is available when the UART (ch.1) clock output is
disabled.
SCK1
UART (ch.1) clock output pin
This pin is available when the UART (ch.1) clock output is
enabled.
UART (ch.1) external clock input pin
This pin is available when the port is in input mode and the UART
(ch.1) specification is external clock mode.
46
P71
E
General-purpose I/O port
This port is always available.
SID1
UART (ch.1) serial data input pin
Since this input is used whenever the UART (ch.1) is in input
operation, the output by any other function must be suspended
unless the output is intentionally performed.
47
P72
E
General-purpose I/O port
This port is available when the UART (ch.1) serial data output is
disabled.
SOD1
UART (ch.1) serial data output pin
This pin is available when the UART (ch.1) serial data output is
enabled.
