H
(CMOS/H)
General purpose I/O ports
This applies in all cases.
INT1,
INT2
External interrupt request input pins
As the inputs operate continuously when external interrupts
are enabled, output to the pins from other functions must
be stopped unless done intentionally.

H
(CMOS/H)
General purpose I/O ports
This applies when output is disabled for reload timers.
INT3
External interrupt request input pins
As the inputs operate continuously when external interrupts
are enabled, output to the pins from other functions must
be stopped unless done intentionally.
TIM4
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.
