The Power-down mode is entered by executing a

If the Watchdog Timer is enabled:
• WDT will be cleared but keeps running
• PD bit in the STATUS register is cleared
• TO bit is set
• Oscillator driver is turned off
• I/O ports maintain the status they had before
For lowest current consumption in this mode, all I/O
pins should be either at V

comparators and CV

or low externally to avoid switching currents caused by
floating inputs. The T0CKI input should also be at V

The first event will cause a device Reset. The two latter
events are considered a continuation of program exe-
cution. The TO and PD bits in the STATUS register can
be used to determine the cause of device Reset. The
PD bit, which is set on power-up, is cleared when Sleep
is invoked. TO bit is cleared if WDT Wake-up occurred.
When the
next instruction (PC + 1) is pre-fetched. For the device
to wake-up through an interrupt event, the correspond-
ing interrupt enable bit must be set (enabled). Wake-up
is regardless of the state of the GIE bit. If the GIE bit is
clear (disabled), the device continues execution at the
instruction after the
set (enabled), the device executes the instruction after
the
address (0004h). In cases where the execution of the
instruction following
