To guarantee that the system oscillator is
started and stabilized, the SST (System
Start-upTimer)providesanextra-delayof1024
system clock pulses when the system 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 enable the SST delay.
The functional unit chip reset status are shown
below.
