Legend:
R = Readable bit
u = Bit is unchanged
‘1’ = Bit is set
W = Writable bit
x = Bit is unknown
‘0’ = Bit is cleared
U = Unimplemented bit, read as ‘0’
-n/n = Value at POR and BOR/Value at all other Resets
bit 7-0
ADPRE<7:0>: Precharge Time Select bits
11111111 = Precharge time is 255 clocks of the selected ADC clock
11111110 = Precharge time is 254 clocks of the selected ADC clock



00000001 = Precharge time is 1 clock of the selected ADC clock
00000000 = Precharge time is not included in the data conversion cycle

Note:
ADACQ<7:0>: Acquisition (charge share time) Select bits
11111111 = Acquisition time is 255 clocks of the selected ADC clock
11111110 = Acquisition time is 254 clocks of the selected ADC clock



00000001 = Acquisition time is 1 clock of the selected ADC clock
00000000 = Acquisition time is not included in the data conversion cycle
If ADPRE is not equal to ‘0’, then ADACQ = b’00000000 means Acquisition time is 256 clocks of the
selected ADC clock.
