Pin no.
Pin name
Circuit
type
Function
17 to 24
P70 to P77
E
General-purpose I/O ports
This function is valid when the output specification for DOT0 to DOT7
is “disabled”.
DOT0 to DOT7
This function is valid when “output compare” output is enabled.
25 to 30
P80 to P85
E
General-purpose I/O ports
This function is valid when the output specification for TOT0 to TOT5
is “disabled”.
TOT0 to TOT5
16-bit reload timer output pins (TOT0 to TOT5)
31, 32
P86, P87
E
General-purpose I/O ports
This function is valid when the PPG0 to PPG1 output specification is
“disabled”.
PPG0, PPG1
PPG timer output pins
This function is valid when the PPG control/status register
specification is “PPG output pins”.
34 to 41
P90 to P97
J
Open-drain I/O ports
This function is valid when the analog input enable register
specification is “port”.
AN08 to AN15
A/D converter analog input pins
This function is valid when the analog input enable register
specification is “analog input”.
46 to 53
P60 to P67
J
Open-drain I/O ports
This function is valid when the analog input enable register
specification is “port”.
AN00 to AN07
A/D converter analog input pins
This function is valid when the analog input enable register
specification is “analog input”.
55
PA0
E
General-purpose I/O port
This function is always valid.
ASR0
ICU input pin
This function is valid during ICU input operations.
56
PA1
E
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.
