LDIA #0000B
OUTA P21; set WDT detection time and clear WDT counter
RESETTING FUNCTION
When CPU in normal working condition and RESET pin holds in low level for three instruction cycles at least,
then CPU begins to initialize the whole internal states, and when RESET pin changes to high level, CPU begins
to work in normal condition.
The CPU internal state during reset condition is as following table :
Hardware condition in RESET state
Program counter
Status flag
Interrupt enable flip-flop ( EI )
MASK0 ,1, 2, 3
Interrupt latch ( IL )
P10, 11, 12, 16, 21, 25, 27, 28, 29, 30
P4, 5, 6, 7, 23, 24

The RESET pin is a hysteresis input pin and it has a pull-up resistor available by mask option.
The simplest RESET circuit is connect RESET pin with a capacitor to V
SS
and a diode to V
