13 / 43 page HT82K95EE/HT82K95AE Rev. 1.50 13 April 13, 2012 extra delay of 1024 system clock pulses when the sys- tem resets (power-up, WDT time-out or RES reset) or when the system awakes from the HALT state. When a system reset occurs, an SST delay is added during the reset period. Any wake up from HALT will en- able the SST delay. The functional unit chip reset status are shown below.
