CZ80PIO Overview
The CZ80PIO, hereinafter referred to as PIO, is a dual-port device which can be programmed by the system software to function as a broad range of peripheral devices that are patible with the Z80CPU such as most keyboards, printers etc. System design is simplified because the PIO connects directly to the Z80CPU with no additional logic. In larger systems, address decoders and buffers may be required.
CZ80PIO Key Features
- Provides a direct interface between Z80 microprocessor systems and peripheral devices Two ports with interrupt-driven ha
- Output Mode (both ports)
- Input Mode (both ports)
- Bi-directional (Port A only)
- Bit Control Mode (both ports) Programmable interrupts on peripheral status conditions
