15
P46
D
This is a general-purpose I/O port.
This function can be set by the port 4 input pull-up resistor setup
register (RDR4) for input. For output, however, this function is
invalid.
SOT1
This is a data output pin for extended I/O serial interface 0.
This function becomes valid when serial data output from SOT1 is
enabled.
16
P47
D
This is a general-purpose I/O port.
This function can be set by the port 4 input pull-up resistor setup
register (RDR4) for input. For output, however, this function is
invalid.
SCK1
This is a serial clock I/O pin for extended I/O serial interface 0.
This function becomes valid when serial clock output from SCK1 is
enabled.
35
P50
D
This is a general-purpose I/O port.
SIN2
This is a data input pin for extended I/O serial interface 1.
Since this input is used as required for serial data input operation,
output by other functions must be suspended except for intentional
operation.
AIN1
This port can be used as count clock A input for 8/16-bit up/down
counter/timer 1.
36
P51
D
This is a general-purpose I/O port.
SOT2
This is a data output pin for extended I/O serial interface 1.
This function becomes valid when serial data output from SOT2 is
enabled.
BIN1
This port can be used as count clock B input for 8/16-bit up/down
counter/timer 1.
37
P52
D
This is a general-purpose I/O port.
SCK2
This is a serial clock I/O pin for extended I/O serial interface 1.
This function becomes valid when serial clock output from serial
SCK2 is enabled.
ZIN1
This port can be used as control clock Z input for 8/16-bit up/down
counter/timer 1.
40,
41
P53,
P54
I
This is a general-purpose I/O port.
DA0,
DA1
These are analog signal output pins for 8-bit D/A converter ch.0
and ch.1.
46 to 53
P60 to P67
K
This is a general-purpose I/O port.
The input function become valid when the analog input enable
register (ADER) is set to select a port.
AN0 to AN7
These are analog input pins of the 8/10-bit A/D converter.
This function is valid when the analog input enable register
(ADER) is enabled.
