Pin no.
Pin name
Circuit type
Function
18
P42
L
(CMOS/H)
General-purpose I/O port
This function is available when the timer output from timer 0 is
disabled.
INT7
External interrupt request input pin
When external interrupts are enabled, these inputs may be used at
any time; therefore, it is necessary to stop output by other functions
on these pins, except when using them for output deliberately.
TIO0
Timer input pin
The data on this pin is used as event count signal for timer 0.
Timer output pin
This function is available when the timer output from timer 0 is
enabled.
19
P43
E
(CMOS/H)
General-purpose I/O port
This function is available when the timer output from timer 1 is
disabled.
TIO1
Timer input pin
The data on this pin is used as event count signal for timer 1.
Timer output pin
This function is available when the timer output from timer 1 is
enabled.
20
P44
E
(CMOS/H)
General-purpose I/O port
This function is available when the timer output from timer 2 is
disabled.
TIO2
Timer input pin
The data on this pin is used as event count signal for timer 2.
Timer output pin
This function is available when the timer output from timer 2 is
enabled.
