Signal Pin # Description
SLEEP# B103 Sleep button. Used by the ACPI operating system to bring the system to sleep state or to wake it
up again.
Note: For proper detection, assert a pulse width of at least 16 ms.

Note
1. Pins are protected on the module by a series schotty diode. Therefore, pull-down resistor is required on the carrier board for proper logic
level.
Table 33 Module Type Definition Signal Description
Signal Pin # Description
TYPE0# C54 The TYPE pins indicate to the Carrier Board the Pin-out Type that is implemented on the module. The pins are tied on
TYPE1# C57 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.

PDS TYPE[0:2]# signals are
available on all modules
following the Type 2-6
Pinout standard.
The conga-TCA3 is
based on the COM
Express Type 6 pinout
therefore the pins 0 and
1 are not connected and
pin 2 is connected to
GND.
