Retains status before halt
(1) When specified as output pin
Current consumption increases if pin
is externally pulled down while it
outputs high level, or externally pulled
up while it outputs low level.
Exercise care in using N-ch open-drain
output (P0A3, P0A2, P1B3 through
P1B0, P2D1, P2D0)
(2) When specified as input pin
Current consumption increases due
to noise if pin is floated
(3) Port 0D (P0D3/AD3 through P0D0/
AD0)
Current consumption increases if pin
is externally pulled up because it is
provided with pull-down resistor
selectable by software
(4) Port 1C (P1C3/AD5, P1C2/AD4,
P1C1/AMIFC, P1C0/FMIFC)
When P1C1/AMIFC or P1C0/FMIFC
pin is used for IF counter, current
consumption increases because
internal amplifier operates
All port pins are set in general-purpose
port mode (except P0D3/AD3 through
P0D0/AD0, P1A3/INT4, P1A2/INT3,
P1C3/AD5, and P1C2/AD4)
Input or output mode of general-purpose
I/O port set before clock stop status is
retained.
(1) When specified as general-purpose
output port
Current consumption increases due
to noise if pin is floated
(2) When specified as general-purpose
input port
Current consumption does not
increase due to noise even if pin is
floated
(3) P1A3/INT4, P1A2/INT3
Set as interrupt pin and current
consumption increases due to external
noise if pin is floated
(4) P0D3/AD3 through P0D0/AD0,
P1C3/AD5, P1C2/AD4
Pin used for A/D converter is retained
as is.
Pull-down resistor of P0D3 through
P0D0 pin retains previous status
Specified as general-purpose output port.
Output contents are retained as is. If pin
is externally pulled down while it outputs
high level or externally pulled up while it
outputs low level, current consumption
increases
