VOLUP/XTALI - Volume-Up Button / Crystal In, Input
This dual function pin is either the volume-up button control input or the crystal oscillator input
pin, depending on system configuration. This pin may also be used as a general purpose input
if its primary function is not needed.
VOLDN/XTALO - Volume-Down Button / Crystal Output, I/O
This dual function pin is either the volume-down button control input or the crystal oscillator
output pin, depending on system configuration. This pin may also be used as a general purpose
input if its primary function is not needed.
12.4 Clock / Miscellaneous
CLKRUN# - Optional System Clock Control, Open Drain Output, Active Low
CLKRUN# is an optional PCI signal defined for mobile operations. This is a Bidirectional pin
indicating that the PCI clock is required. This signal pin is not available on the add-in card
connector.
CRYVDD - Crystal & PLL Power Supply
Power pin for crystal oscillator and internal phase locked loop. This pin must be connected to a
nominal +3.3 Volts.
CRYGND - Crystal & PLL Ground Supply
Ground pin for crystal oscillator and internal phase locked loop.
JACX, JACY, JBCX, JBCY - Joystick A and B X/Y Coordinates, I/O
These pins are the 4 axis coordinates for the joystick port. These pins may also be used as
general purpose inputs or open drain outputs if their primary function is not needed.
JAB1/SDO2 - Joystick A Button 1 / Serial Data Output 2, I/O
This dual function pin defaults as JAB1 (button 1 input for joystick A). In non-AC ’97 system
configurations, this pin can function as a second stereo digital data output pin if enabled. This
pin can also be a general purpose polled input if a second data output stream is not required.
JAB2/SDO3 - Joystick A Button 2 / Serial Data Output 3, I/O
This dual function pin defaults as JAB2 (button 2 input for joystick A). In non-AC ’97 system
configurations, this pin can function as a third stereo digital data output pin if enabled. This pin
can also be a general purpose polled input if a third data output stream is not required.
JBB1/LRCLK - Joystick B Button 1 / L/R Framing Clock, I/O
This dual function pin defaults as JBB1 (button 1 input for joystick B). In non-AC ’97 system
configurations, this pin can function as a left/right framing clock output pin for SDO2 and
SDO3. This pin can also be used as a general purpose polled input if alternate data output
streams are not required.
