Overview
The Z80 PIO module (SC103) provides two 8-bit parallel ports with handshaking and
flexible input and output connectivity, as well as support for Z80 mode 2 interrupt
daisy chaining.
Each port has eight bidirectional data lines and two handshaking lines. The PIO has
flexible interrupt generation and fully supports Z80 mode 2 interrupts.
For full details of the Z80 PIO see the Zilog data sheet.
