Description

Note 1:

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

(Register 6-1).

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.
