Separate PVCC and AVCC Supply Support
Supplying a voltage of AVCC that is lower than PVCC (for example PVCC = 24 V and AVCC = 12 V),
reduces the power dissipation on the internal LDO. This gives customers the flexibility to choose between
the extreme, low-idle current mode (J3: 1 and 2 set to IN, with separate AVCC) and single power supply
mode (J3: 2 and 3 set to IN, without AVCC).
