(M) pin 69; (Q) pin 91
Power pin for crystal oscillator and internal phase locked loop.
(M) pin 72; (Q) pin 94
Ground pin for crystal oscillator and internal phase locked loop.
(M) pins 52, 53, 54, 55; (Q) pins 66, 67, 68, 69
These pins are the 4 axis coordinates for the joystick port. These pins may also be used as a
general purpose inputs or open drain outputs if their primary function is not needed.
(M) pin 56; (Q) pin 70
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.
(M) pin 57; (Q) pin 71
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.
(M) pin 58; (Q) pin 72
This dual function pin defaults as JBB1 (button 1 input pin for joystick B). In non-AC’97
system configurations, this pin can function as an alternate 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.
(M) pin 59; (Q) pin 73
This dual function pin defaults as JBB2 (button 2 input pin for joystick B). In non-AC’97
system configurations, this pin can function as a master (256x sample rate) output clock if
enabled. This pin can also be used as a general purpose polled input if alternate data output
streams are not required.
(M) pin 60; (Q) pin 74
This is the serial input pin for the internal MIDI port.
