To guarantee that the crystal oscillator is
started and stabilized, the SST (System
Start-upTimer)providesanextra-delayof1024
system clock pulses when the system powers up
or awakes from the HALT state. Awaking from
the HALT state or system power-up, the SST
delay is added.
An extra SST delay is added during the
power-up period, and any wake-up from HALT
may enable the SST delay only.
The functional unit chip reset status are shown
below.
