Note 1: The registers are unsigned, however their sign is kept as a separate bit in the System Status Register.
2: These registers are reserved for EMI filter compensation when necessary for power supply monitoring.
They may require specific adjustment depending on PSU parameters, please contact the local Microchip
office for further support.
3: The Overtemperature event is only available on system versions 0xFA14 and later.
