ADFM: A/D Result Format Select bit

1 = Right justified. Six Most Significant bits of ADRESH are read as ‘0’.

0 = Left justified. Six Least Significant bits of ADRESL are read as ‘0’.

ADCS2: A/D Clock Divide by 2 Select bit

1 = A/D clock source is divided by 2 when system clock is used

0 = Disabled

Note: The ANSEL bits for AN3 and AN2 inputs must be configured as analog inputs for the

VREF+ and VREF- external pins to be used.

Unimplemented: Read as ‘0’

Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

‘1’ = Bit is set

U = Unimplemented bit, read as ‘0’

‘0’ = Bit is cleared x = Bit is unknown
