  • Page 64: Sema Functions

    Board Specific SEMA functions Voltages The BMC of the LEC-BTS implements a Voltage Monitor and samples several Onboard Volt- ages. The Voltages can be read by calling the SEMA function, “Get Voltages”. The function returns a 16-bit value divided in Hi-Byte (MSB) and Lo-Byte (LSB).
  • Page 65 LEC-BTS Main Current The BMC of the LEC-BTS 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 Hi-Byte (MSB) and Lo-Byte (LSB). These four values represent the last four currents drawn by the board.

  • Page 66: Watchdog Timer

    Watchdog Timer The LEC-BTS 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.
