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 = Select ANx for input scan
0 = Skip ANx for input scan
Note 1: On devices with less than 32 analog inputs, all ADxCSSH bits can be selected by user software. However,
inputs selected for scan without a corresponding input on device convert V
REFL.
2: CSSx = ANx, where x = 16-31.
3: ADC2 only supports analog inputs AN0-AN15; therefore, no ADC2 Input Scan Select register exists.
