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 CSS31: ADC1 Input Scan Selection bit
1 = Selects CTMU capacitive and time measurement for input scan (Open)
0 = Skips CTMU capacitive and time measurement for input scan (Open)
bit 14 CSS30: ADC1 Input Scan Selection bit
1 = Selects CTMU on-chip temperature measurement for input scan (CTMU TEMP)
0 = Skips CTMU on-chip temperature measurement for input scan (CTMU TEMP)
bit 13-11 Unimplemented: Read as ‘0’
bit 10 CSS26: ADC1 Input Scan Selection bit
(2)
1 = Selects OA3/AN6 for input scan
0 = Skips OA3/AN6 for input scan
bit 9 CSS25: ADC1 Input Scan Selection bit
(2)
1 = Selects OA2/AN0 for input scan
0 = Skips OA2/AN0 for input scan
bit 8 CSS24: ADC1 Input Scan Selection bit
(2)
1 = Selects OA1/AN3 for input scan
0 = Skips OA1/AN3 for input scan
bit 7-0 Unimplemented: Read as ‘0’
Note 1: All AD1CSSH bits can be selected by user software. However, inputs selected for scan, without a
corresponding input on the device, convert V
REFL.
2: The OAx input is used if the corresponding op amp is selected (OPMODE (CMxCON<10>) = 1);
otherwise, the ANx input is used.
