CTS0#, CTS1# Input Clear to send.
RTS0#, RTS1# Output Request to send.
DTR0#, DTR1# Output Data terminal read.
2.2.14. KEYBOARD/MOUSE INTERFACE
INIT# Initialize Printer. This output sends an
initialize command to the connected printer.
AUTOFD# Automatic Line feed. This output sends
a command to the connected printer to
automatically generate line feed on received
carriage returns.
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.
SLCTIN# Select In. Printer select output.
PPD[7-0] Parallel Port Data Lines Data transfer
lines to printer. Bidirectional depending on modes.
KBDATA, Keyboard Data Line. 11-bits of data are 2.2.16. MISCELLANEOUS
shifted serially through this line when data is being
transferred. Data is synchronised to KBCLK.
SPKRD Speaker Drive. This is the output to the
speaker and is the AND of the counter 2 output
MCLK, Mouse Clock line. Mouse data is latched with bit 1 of Port 61h and drives an external

t(s MDATA, Mouse Data Line. 11-bits of data are
c shifted serially through this line when data is being
u transferred. Data is synchronised to MCLK.
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.

te P Table 2-4. Multiplexed Signals (on the same pin)
TRST Test reset input
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.
