The shortest period is 20mS; user can extend the WDT overflow period to 2.6S by using prescaler. Power-On Reset & Power-Down Reset Reset Timer: 20 mS (5V) Four external Oscillate modes: RC,LP Crystal,NT Crystal and HS Crystal. Two operation modes: General mode, and Advanced mode Operation Voltage: 2.2V¡ã 5.5V Instruction set: 79 Wake-up: Watchdog timer overflow, Port A (PA3~ PA0) Reset vector: 7FFH IRQ vector: 7FEH Low voltage reset: voltage shortage will result in reset 1 tenx technology, inc.
