Smart Embedded Management Agent (SEMA)
6.1.2. Main Current
The BMC implements a current monitor. The current can be read by calling the SEMA function “Get Main Current”.
The function returns four 16-bit values divided in high-byte (MSB) and low-byte (LSB). These 4 values represent
the last 4 currents drawn by the board. The values are sampled every 250ms. The order of the 4 values is NOT in
chronological order. Access by the BMC may increase the drawn current of the whole system. In this case, there
are still 3 samples not influenced by the read access.
Main Current = (MSB_n<<8 + LSB_n) x 8.06mA
6.1.3. BMC Status
This register shows the status of BMC controlled signals on the AmITX-SL.

0 WDT_OUT
1 LVDS_VDDEN
2 SPI_HEADER_EN
3 BIOS_MODE
4 POSTWDT_DISn
5 SEL_BIOS
6.1.4. Exception Codes
In case of an error, the BMC drives a blinking code on the blue Status LED (LED1). The same error code is also
reported by the BMC Flags register. The Exception Code is not stored in the Flash Storage and is cleared when the
power is removed. Therefore, a “Clear Exception Code” command is not needed or supported.
