13 / 48 page ![]() HT46R23/HT46C23 Rev. 1.60 13 May 3, 2004 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. The functional unit chip reset status are shown below. An extra option load time delay is added during system reset (power-up, WDT time-out at normal mode or RES reset). PC 000H Interrupt Disable WDT Clear. After master reset, WDT begins counting Timer/Event Counter Off Input/Output Ports Input mode SP Points to the top of the stack The registers states are summarized in the following table.
