65xx 8-bit Peripheral Interface Adapter (PIA)

The W65C21 Peripheral Interface Adapter (PIA), a flexible I/O device, has been used successfully with many different microprocessor families especially the 65xx, 68xx/68xxx and x86 microprocessors. Two program controlled 8–bit bi–directional (bit programmable) peripheral I/O ports allow direct interfacing between the microprocessor and selected peripheral units with manual or interrupt driven hand–shaking. The W65C21 is available in both CMOS and NMOS compatible versions
