Descriptions

1.8V power/ground for internal logic

1.8V power/ground for analog circuitry

3.3V power/ground for external interface logic

1.8V analog output (A capacitor is connected between the pin and analog ground)

Oscillator cell width enable and feedback resistor (6 M – 40 MHz)

Oscillator cell width enable and feedback resistor (– 100 kHz)

3.3V interface LVCMOS schmitt trigger level input buffers

resistor with control, tri-state, Io = 4 mA

3.3V bi-directional pad, LVCMOS schmitt trigger, 50 KΩ pull-up resistor with

control, tri-state, Io = 8 mA

3.3V bi-directional pad, LVCMOS schmitt trigger, 50 KΩ pull-up resistor with

control, tri-state, Io = 12 mA

3.3V input buffer

3.3V output buffer with tri-state

3.3V bi-directional buffer with input and tri-state output

3.3V bi-directional buffer with input and open-drain output, tri-state

NOTES:

1. ENDIAN value is latched only at the rising edge of nRESET: when nRESET is Low, the ENDIAN (GPC3) pin operates in

input mode; nRESET becomes High, the ENDIAN pin will automatically switch to output mode.

2. IICSDA, IICSCLK, PCI_nSERR, and PCI_nINTA pins are of open-drain type.

3. AI/AO means analog input/output.
