Watchdog Timer

The LEC-BT features three separate Watchdog Timers. One of them is integrated in the SoC
and two are provided by the BMC (managed by the SEMA).

The SoC Watchdog can be configured in the BIOS or by programming the Watchdog registers.
If this function is used by user application, the application has to provide all logging functionality
if desired.

The BMC Watchdog activations are caused by under voltage protection. The Watchdog LED
flashes after restart but only if the power supply reaches 4.2V.

4.4

Temperature Sensors

The LEC-BT supports two temperature sensor functions. One is offered from the SoC and one
from a dedicated chip (Texas Instruments LM73) on the board.

The SoC temperature sensors can be configured by programming the appropriate SoC regis-
ters. Refer to the Thermal Management chapter in the Intel Atom E3800 data sheet for more
information. The on-board LM73 temperature sensor is managed by the BMC and is configured
through the SEMA utility.

Programming Examples

Programming examples can be provided based on a Linux operating system, upon request.
