This device monitors the SoC error output signal at its nERR_SOC input pin. In error condition, ESM toggles its nRSTOUT_SOC pin to reset the SoC.

Depending on the current operational mode, some voltage domains remain energized while others can be off. This PFSM is also used to trigger a firmware update, and provides R/W access to device registers.
