Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15-0 CSS<31:16>: ADC Input Scan Selection bits
(1, 2)
1 = Select ANx for input scan
0 = Skip ANx for input scan
Note 1: On devices with less than 32 analog inputs, all ADxCSSL bits can be selected by user. However, inputs
selected for scan without a corresponding input on device convert V
REF-.
2: ADC 2 only supports analog inputs AN0-AN15; therefore, no ADC 2 Input Scan Select register exists.
