Note 1:

The registers are unsigned, however their sign is kept as a separate bit in the System Status register.

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.
