6.1.3.5
Watchdog
The conga-TCA3 is equipped with a multi stage watchdog solution that is triggered by software. The COM Express™ Specification does
not provide support for external hardware triggering of the Watchdog, which means the conga-TCA3 does not support external hardware
triggering.
For more information about the Watchdog feature, see section 10.4.1 "Watchdog Submenu" and also application note AN3_Watchdog.pdf
on the congatec AG website at www.congatec.com.
Note
The conga-TCA3 module does not support the watchdog NMI mode. COM Express type 6 modules do not support the PCI bus and therefore
the PCI_SERR# signal is not available. There is no way to drive an NMI to the processor without the presence of the PCI_SERR# PCI bus signal.
6.1.3.6
I
2
C Bus
The conga-TCA3 offers support for the frequently used I
2
C bus. Thanks to the I
2
C host controller in the cBC the I
2
C bus is multimaster capable
and runs at fast mode.

OEM BIOS Customization
The conga-TCA3 is equipped with congatec Embedded BIOS, which is based on American Megatrends Inc. Aptio UEFI firmware. The congatec
Embedded BIOS allows system designers to modify the BIOS. For more information about customizing the congatec Embedded BIOS, refer to
the congatec System Utility user’s guide CGUTLm1x.pdf on the congatec website at www.congatec.com or contact technical support.
The customization features supported are described below:
6.2.1
OEM Default Settings
This feature allows system designers to create and store their own BIOS default configuration. Customized BIOS development by congatec for
OEM default settings is no longer necessary because customers can easily perform this configuration by themselves using the congatec system
utility CGUTIL. See congatec application note AN8_Create_OEM_Default_Map.pdf on the congatec website for details on how to add OEM
default settings to the congatec Embedded BIOS.
