6.2.3
Power Loss Control
The cBC has full control of the power-up of the module and therefore can be used to specify the behavior of the system after an AC power loss
condition. Supported modes are “Always On”, “Remain Off” and “Last State”.
6.2.4
Watchdog
The conga-MA5 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; therefore, the conga-MA5 does not support external hardware triggering.
For more information about the Watchdog feature, refer to the application note AN3_Watchdog.pdf at www.congatec.com.
6.2.5
General Purpose Input/Output
The conga-MA5 offers general purpose inputs and outputs for custom system designs. These GPIOs are multiplexed with SD signals and are
controlled by the cBC.
6.3
OEM BIOS Customization
The conga-MA5 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:
6.3.1
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.
