SLOT_2_ENB
If set then D_V
DD / 2 or BB_VDD (depending on SLOT2_VBB) is sampled
into SAR slot 2 which also activates the SAR ADC.
4
SLOT_3_ENB
If set then A_V
DD / 2 is sampled into SAR slot 3 which also activates the
SAR ADC.
5
SLOT_2_VBB
If set then BB_V
DD input is used as input to SAR slot 2 rather than the
D_V
DD.
