GENERAL DESCRIPTION
The
programmed to support the IBM compatible
personal computer keyboard serial interface. The
keyboard controller receives serial data from the
keyboard, checks the parity of the data,
translates the scan code, and presents the data
to the system as a byte of data in its output
buffer. The controller will interrupt the system
when data is placed in its output buffer. The byte
of data will be sent to the keyboard serially with
an odd parity bit automatically inserted. The
keyboard is required to acknowledge all data
transmissions. No transmission should be sent to
the keyboard until acknowledgment is received
for the previous byte sent.
KBD42W11
keyboard
controller
is
The KBD42W11 keyboard controller and BIOS to
improve the performance of IBM PC machines
and their compatibles. A hardwire methodology
is used in this keyboard controller instead of a
software implementation, as in the traditional
8042 keyboard BIOS. This enables the keyboard
controller to respond instantly to all commands
sent from the keyboard to the CPU BIOS.
The KBD42W11 enables popular programs such
as AutoCAD
, Microsoft
Windows, NOVELL
,
and other programs to run much faster.
