VREF+, VREF- inputs can be multiplexed

with other analog inputs.

Channels 1, 2 and 3 are not applicable

for the 12-bit mode of operation.

For dsPIC33EPXXX(GP/MC/MU)806 and

PIC24EPXXXGP806 devices, y = 0-15

and 24-31; for ADC2, y = 15; for all others,

y = 32.

When ADDMAEN (ADxCON4<8>) = 1,

enabling DMA, only ADCxBUF0 is used.
