The WDT time-out during HALT is different from other
chip reset conditions, since it can perform a warm re -
set thatresetsonlythePCandSP,leavingtheothercir-
cuits in their original state. Some registers remain un-
changed during other reset conditions. Most registers
are reset to the initial condition when the reset condi-
tions are met. By examining the PDF and TO flags, the
programcandistinguishbetweendifferent chipresets .

To guarantee that the system oscillator is started and
stabilized, the SST (System Start-up Timer) provides an
extra-delay of 1024 system clock pulses when the sys-
tem reset (power-up, WDT time-out or RES reset) or the
system awakes from the HALT state.
When a system reset occurs, the SST delay is added
during the reset period. Any wake-up from HALT will en-
able the SST delay.
