MC68HC04J3 - 8-Bit Microcontroller
VDD AND VSS Power is supplied to the microcomputer 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 microcomputer.
A pullup resistor on this pin is a manufacturing mask option.
