H
(CMOS/H)
General purpose I/O ports
This applies when output is disabled for reload timers.
INT7,
INT0
External interrupt request input pin
As the input operates continuously when the external
interrupt is enabled, output to the pin from other functions
must be stopped unless done intentionally.
TIM0,
TIM1
I/O pins for reload timers
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.

D
(CMOS/H)
General purpose I/O ports
This applies when output is disabled for reload timers.
TIM2,
TIM3
I/O pins for reload timers
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.

P84
D
(CMOS/H)
General purpose I/O port
This applies in all cases.
SIN0
Serial data input pin for UART0
As the input operates continuously when UART0 is set to
input operation, output to the pin from other functions must
be stopped unless done intentionally.
54
56
P85
D
(CMOS/H)
General purpose I/O port
This applies when serial data output is disabled for UART0.
SOT0
Serial data output pin for UART0
This applies when serial data output is enabled for UART0.
55
57
P86
D
(CMOS/H)
General purpose I/O port
This applies when the UART0 clock output is disabled.
SCK0
Clock I/O pin for UART0
This applies when the UART0 clock output is enabled.
As the input operates continuously when UART0 is set to
input operation, output to the pin from other functions must
be stopped unless done intentionally.

P90
D
(CMOS/H)
General purpose I/O port
This applies in all cases.
SIN1
Serial data input pin for UART1
As the input operates continuously when UART1 is set to
input operation, output to the pin from other functions must
be stopped unless done intentionally.
