Separate PVCC or AVCC Supply Support
By supplying a voltage of AVCC which is lower than PVCC (for example, PVCC = 24 V and AVCC = 12
V), the power dissipation on the internal LDO is reduced. This gives customers the flexibility to choose
between 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).
