MC68HC04J3 Datasheet (Motorola) - 8-Bit Microcontroller

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.
