W83C43 Description
The W83C43 is a keyboard controller designed to provide the functions needed to interface a CPU to a keyboard or to a PS/2 mouse. The W83C43 can be used with IBM®-patible personal puters or PS/2-based systems. The 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.
