V
SS
If this pin remains "H" for at least one machine cycle, the MSM80C154S/MSM83C154S is reset.
Since this pin is pulled down internally, a power-on reset is achieved by simply connecting a
capacitor between V
CC
and this pin.
Oscillator inverter input pin. External clock is input through XTAL1 pin.
Oscillator inverter output pin.
Power supply pin during both normal operation and standby operations.
GND pin.
