55
PA0
C
General-purpose I/O port
This function is always valid.
ASR0
ICU (input capture unit) input pin
This function is valid during ICU (input capture unit) input operations.
56
PA1
C
General-purpose I/O port
This function is always valid.
PWC0
PWC input pin
During PWC0 input operations, this input may be used suddenly at
any time; therefore, it is necessary to stop output by other functions
on this pin, except when using it for output deliberately.
POT0
PWC output pin
This function is valid during PWC output operations.
57 to 59
PA2 to PA4
C
General-purpose I/O ports
This function is always valid.
PWC1 to PWC3
PWC input pins
This function is valid during PWC input operations.
During PWC1 to PWC3 input operations, this input may be used
suddenly at any time; therefore, it is necessary to stop output by other
functions on this pin, except when using it for output deliberately.
POT1 to POT3
PWC output pins
This function is valid during PWC output operations.
ASR1 to ASR3
ICU (input capture unit) input pins
This function is valid during ICU (input capture unit) input operations.
60,
61
PA5,
PA6
B
General-purpose I/O ports
This function is always valid.
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
CC
/V
SS
level to
use these pins in input mode.
INT0,
INT1
DTP/External interrupt request input pins
When DTP/external interrupts are enabled, these inputs may be used
suddenly at any time; therefore, it is necessary to stop output by other
functions on these pins, except when using them for output
deliberately.
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
CC
/V
SS
level to
use these pins in input mode.
62
PA7
B
General-purpose I/O port
This function is always valid.
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
CC
/V
SS
level to
use these pins in input mode.
