    Express-BD74 5. Smart Embedded Management Agent (SEMA) The onboard microcontroller (BMC) implements power sequencing and Smart Embedded Management Agent (SEMA) functionality. The microcontroller communicates via the System Management Bus with the CPU/chipset. The following functions are implemented: ‧ Total operating hours counter. Counts the number of hours the module has been run in minutes.

  • Page 40: Board Specific Sema Functions

    5.1.2. Main Current The BMC of the Express-BD74 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.
