33 to 40
25 to 32
P00 to P07
B
(CMOS)
General-purpose I/O ports.
41 to 48
33 to 40
P10 to P17
B
(CMOS)
General-purpose I/O ports.
49 to 52

P20 to P23
B
(CMOS)
General-purpose I/O ports.
53 to 56
45 to 48
P24 to P27
G
(CMOS)
General-purpose I/O ports.
This function is activated when the output specification of the
reload timer is “disabled”.
TIM0 to TIM3
I/O pins for reload timers 0 to 4.
Input is used only as necessary while serving as input for the
reload timer. It is therefore necessary to stop output
beforehand using other functions unless intentionally used
otherwise.
Their function as output terminals for the reload timer is
activated when the output specification is “enabled”.
INT4 to INT7
External interrupt request input pins.
Input is used only as necessary while external interrupts are
enabled. It is therefore necessary to stop output beforehand
using other functions unless intentionally used otherwise.
22 to 25
14 to 17
P30 to P33
B
(CMOS)
General-purpose I/O ports.
3
59
P40
E
(CMOS/H)
General-purpose I/O port.
This function is always enabled.
SIN
UART serial data input pin.
Input is used only as necessary while serving as UART input.
It is therefore necessary to stop output beforehand using other
functions unless intentionally used otherwise.
4
60
P41
E
(CMOS/H)
General-purpose I/O port.
This function is activated when the serial data output
specification of the UART is “disabled”.
SOT
UART serial data output pin.
This function is activated when the serial data output
specification of the UART is “enabled”.
