• WDT will be cleared but keeps running

• TO bit is set

• I/O ports maintain the status they had before

The first event will cause a device RESET. The two
latter events are considered a continuation of program
execution. 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
