4.5. I/O Behaviour in Shutdown
During Shutdown mode, the I/O pins are switched into dedicated states:
Ports/Pins Port function Setting
P00_0 to P00_7,
P01_0 to P01_7,
P02_0 to P02_7,
P03_0 to P03_7.
P08_6, P08_7,
P10_5, P13_0
P04_0 to P04_1,
P05_0 to P05_7,
P06_0 to P06_7,

The pins are switched to input direction, but it is not possible
to input signals on these pins.
If STCR.HIZ (HiZ mode in STOP) is not set, the pull-up/pulldown
settings are maintained during shutdown.
If STCR.HIZ is set, the pull-up and pull-down resistors are
disabled.
If the pins were switched to output direction before shutdown
(by PFR==1 or DDR==1), the pins will output ‘1’ value and
the driver strength is switched to 2 mA.
Otherwise, the pins keep input direction, but it is not possible
to input signals on these pins. If STCR.HIZ is not set, the
pull-up/pull-down settings are maintained. If STCR.HIZ is
set, the pull-up and pull-down resistors are disabled.
The pins are switched to input direction.
If STCR.HIZ is not set, the pull-up/pull-down settings are
maintained during shutdown. If STCR.HIZ is set, the pull-up
and pull-down resistors are disabled.
If external interrupt is enabled for recovery from Shutdown
(Shutdown INTE=1), the input threshold setting (PILR,
EPILR) is maintained during the shutdown mode and it is
possible to input signals for recovery. After the first recovery
factor is accepted, the port settings are initialized when the
device proceeds to the reset (INIT/RST) sequence.
All other pins are switched to input direction, but it is not possible
to input signals on these pins. If STCR.HIZ is not set,
the pull-up/pull-down settings are maintained during Shutdown.
If STCR.HIZ is set, the pull-up and pull-down resistors
are disabled.
ALARM_0 ALARM analog input The state of ALARM input is not changed in Shutdown state.
MD_0 to MD_2 Mode inputs The state of MD[2:0] is not changed in Shutdown state
INITX External INIT
VCC18C Regulator capacitor pin
The state of INITX is not changed in Shutdown state. The
pull-up is enabled. It is possible to input external INITX signal
during Shutdown.
The capacitor connection pin for internal regulator shows the
voltage which is applied to internal Always-ON domain.
