Previous status before halt status is
set is retained as is.
(1)
In output mode
Current consumption increases
if these pins are externally pulled
down while they output high level,
or externally pulled up while they
output low level.
Pay attention to N-ch open-drain
output pins (P0A

, and
P1B

Current consumption increases
if these pins are externally pulled
up because they have pull-down
resistor.
However, pull-down resistor of
pin selected as A/D converter
pin is OFF.

AMIFC pins are used for IF
counter because internal amplifier
operates.
Because IF counter is not
automatically disabled even if
CE pin goes low, it must be
initialized by program as
necessary.
Ports 1D and 1A are designed to
prevent increase in current
consumption due to noise even
if they are set in general purpose
input port mode and floated.

Current consumption increase due to external noise if this pin is floated.
All these pins are set in general-purpose
input port mode.
All input ports, except port 0C (P0C
3
-
P0C
0
), are designed to prevent increase
in current consumption due to noise
even if they are externally floated.
Port 0C (P0C
3
-P0C
0
) must be externally
pulled down or up so that current
consumption does not increase due
to noise.
Port 0D (P0D
3
/ADC

-P0D
0
/ADC
2
) is
internally pulled down.
These pins are set in general-purpose
output port pins.
Output contents are retained as is.
Therefore, current consumption
increases if these pins are externally
pulled down while they output high
level, or pulled up while they output
low level.
