input
General-purpose I/O ports.
SIN1
Serial data input pin for UART channel 1. While UART
channel 1 is operating for input, the input of this pin is
used as required. This pin must not be used for any
other input.
CMOS input can be selected by user program.
AN10
A/D converter analog input pins. This function is
enabled when the analog input is specified (ADER1).
75

P73
K
General-purpose I/O ports.
SOT1
Serial data output pin for UART channel 1. This func-
tion is enabled when data output of UART channel 1
is specified.
AN11
A/D converter analog input pins. This function is
enabled when the analog input is specified (ADER1).
74

P74
K
General-purpose I/O port.
SCK1
Serial clock I/O pin for UART channel 1. This function
is enabled when clock output of UART channel 1 is
specified.
AN12
A/D converter analog input pins. This function is
enabled when the analog input is specified (ADER1).

General-purpose I/O ports.
IN0, IN1
Trigger input pins for input capture channels 0, 1.
When input capture channels 0, 1 are used for
input operation, these pins are enabled as required
and must not be used for any other input.
AN14,
AN15
A/D converter analog input pins. This function is
enabled when the analog input is specified (ADER1).
