Copy of Sock Master's

The heart of the Deluxe RS-232 Pak is the Synertek 6551 ACIA. It has an on-chip baud rate generator, programmable interrupts and status register for ease of operation, false start bit detection, and echo mode

This ACIA board is memory mapped to addresses $FF68 (65384) to $FF6B (65387).

The 6551 uses 4 memory addresses for the following functions:

Address Write Read
FF68 Transmit data Register Received data Register
FF69 Soft Reset Status Register
FF6A Command Register
FF6B Control Register
