2.2.14. KEYBOARD/MOUSE INTERFACE
KBCLK, Keyboard Clock line. Keyboard data is
latched by the controller on each negative clock
edge produced on this pin. The keyboard can be
disabled by pulling this pin low by software control.
KBDATA, Keyboard Data Line. 11-bits of data are
shifted serially through this line when data is being
transferred. Data is synchronised to KBCLK.
MCLK, Mouse Clock line. Mouse data is latched
by the controller on each negative clock edge
produced on this pin. The mouse can be disabled
by pulling this pin low by software control.
MDATA, Mouse Data Line. 11-bits of data are
shifted serially through this line when data is being
transferred. Data is synchronised to MCLK.
2.2.15. PARALLEL PORT
PE Paper End. Input status signal from printer.
SLCT Printer Select. Printer selected input.
BUSY# Printer Busy.
Input status signal from printer.
ERR# Error. Input status signal from printer.
ACK# Acknowledge.
Input status signal from printer.
PDDIR# Parallel Device Direction.
Bidirectional control line output.
STROBE# PCS/Strobe#.
Data transfer strobe line to printer.

PCMCIA Pin Names
INIT# Initialize Printer. This output sends an
initialize command to the connected printer.
AUTOFD# Automatic Line feed. This output sends
a
automatically generate line feed on received
carriage returns.
SLCTIN# Select In. Printer select output.
PPD[7-0] Parallel Port Data Lines Data transfer
lines to printer. Bidirectional depending on modes.
2.2.16. MISCELLANEOUS
SPKRD Speaker Drive. This is the output to the
speaker and is the AND of the counter 2 output
with bit 1 of Port 61h and drives an external
speaker driver. This output should be connected to
a 7407 type high voltage driver.
SCAN_ENABLE Reserved. This pin is reserved
for Test and Miscellaneous functions. It has to be
set to ‘0’ or connected to ground in normal
operation.

2.3 SIGNAL DETAIL
The muxing between ISA, LOCAL BUS and
PCMCIA is performed by external strap options.
The resulting interface is then dynamically muxed
with the IDE Interface.
