3rd Sample Differential Input Select
Description
Value
The analog inputs are not differentially sampled.
0
The analog input is differentially sampled. The corresponding
ADCSSMUXn nibble must be set to the pair number "i", where
the paired inputs are "2i and 2i+1".

2nd Sample Interrupt Enable
Description
Value
The raw interrupt is not asserted to the interrupt controller.
0
The raw interrupt signal (
INR0
bit) is asserted at the end of the
second sample's conversion. If the
MASK0
bit in the ADCIM
register is set, the interrupt is promoted to the interrupt controller.
