MC68HC04J2 - 8-Bit Microcontroller
VOD AND VSS Power is supplied to the MCU using these two pins.
VDD is power, and VSS is ground.
IRQ This pin provides the capability for asynchronously ap- plying an external interrupt to the MCU.
A pull-up resistor on this pin is a manufacturing mask option.
EXTAl AND XTAl These pins provide contro
