GENERAL DESCRIPTION
The W83C45 is an 80C42 based keyboard and mouse controller. It is designed to provide the
functions needed to interface a CPU to a keyboard or to a PS/2 mouse, and can be used with IBM
-
compatible personal computers or PS/2-based systems. The W83C45 incorporates 2K byte software
ROM BIOS, and 256 byte data RAM. The W83C45 controller receives serial data from the keyboard
or PS/2 mouse, checks the parity of the data, and presents the data to the system as a byte of data in
its output buffer. The controller will interrupt the system when data are placed in its output buffer. The
keyboard and PS/2 mouse are required to acknowledge all data transmissions. No transmission
should be sent to the keyboard or PS/2 mouse until the acknowledge signal is received for the
previous byte sent.
