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.

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).
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.

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.
