(M) pins 50, 39, 31, 21, 8, 100, 94, 86;
(Q) pins 58, 47, 39, 29, 8, 128, 122, 114
PCIVDD pins are the PCI driver power supply pins.
(M) pins 49, 40, 30, 22, 7, 1, 93, 87;
(Q) pins 57, 48, 38, 30, 7, 1, 121, 115
PCIGND pins are the PCI driver ground reference pins.
(M) pin 51; (Q) pin 65
This pin is sampled at reset for test mode entry. If it is high at reset, test mode is enabled. This
pin should normally be pulled to ground in a production design.
(M) pin 80; (Q) pin 102
Data line for external serial EEPROM containing device configuration data. When used with an
external EEPROM, a 4.7 k
requirements, this pin can be used as a general purpose input or open drain output.
(M) pin 79; (Q) pin 101
Clock line for external serial EEPROM containing device configuration data. In designs
without EEPROM requirements, this pin can be used as a general purpose output pin.
(M) pin 66; (Q) pin 88
This dual function pin defaults as a general purpose I/O pin. In non-AC’97 system
configurations, this pin can function as a second stereo digital data input pin if enabled.
(M) pin 70; (Q) pin 92
This dual function pin is either the volume up button control input or the crystal oscillator input
pin, depending on system configuration. When a crystal is used, it must designed for
fundamental mode, parallel resonant. This pin may also be used as a general purpose input if its
primary function is not needed.
(M) pin 71; (Q) pin 93
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.
pullup resistor is required. In designs without EEPROM
