Description
PCI Reset output, active low.
PCI Lock control line, active low.
System Error: SERR# may be pulsed active by any
PCI device that detects a system error condition.
PCI Power Management Event: PCI peripherals drive
PME# to wake system from low-power states S1–S5.
Bidirectional pin used to support PCI clock run
protocol for mobile systems.
PCI interrupt request lines
PCI 33MHz clock output
Module input signal indicates whether an off-Module
PCI device is capable of 66MHz operation. Pulled to
GND by Carrier Board device or by Slot Card if the
devices are NOT capable of 66 MHz operation.
If the Module is not capable of supporting 66 MHz PCI
operation, this input may be a no-connect on the
Module.
If the Module is capable of supporting 66 MHz PCI
operation, and if this input is held low by the Carrier
Board, the Module PCI interface shall operate at 33
MHz.
Description
The TYPE pins indicate to the Carrier Board the Pin-out Type that is
implemented on the module. The pins are tied on the module to either
ground (GND) or are no-connects (NC). For Pinout Type 1, these
pins are don't care (X).

The Carrier Board should implement combinatorial logic that monitors
the module TYPE pins and keeps power off (e.g deactivates the
ATX_ON signal for an ATX power supply) if an incompatible module
pin-out type is detected. The Carrier Board logic may also implement
a fault indicator such as an LED.
