Read = 0b.
ADC0 Accumulate Enable.
Function
Enables multiple conversions to be accumulated when burst mode is disabled.
0: ADC0H:ADC0L contain the result of the latest conversion when Burst Mode is
disabled.
1: ADC0H:ADC0L contain the accumulated conversion results when Burst Mode
is disabled. Software must write 0x0000 to ADC0H:ADC0L to clear the accumu-
lated result.
This bit is write-only. Always reads 0b.
5:3
AD0SJST[2:0]
ADC0 Accumulator Shift and Justify.
Specifies the format of data read from ADC0H:ADC0L.
000: Right justified. No shifting applied.
001: Right justified. Shifted right by 1 bit.
010: Right justified. Shifted right by 2 bits.
011: Right justified. Shifted right by 3 bits.
100: Left justified. No shifting applied.
All remaining bit combinations are reserved.
2:0
AD0RPT[2:0]
ADC0 Repeat Count.
Selects the number of conversions to perform and accumulate in Burst Mode.
This bit field must be set to 000 if Burst Mode is disabled.
000: Perform and Accumulate 1 conversion.
001: Perform and Accumulate 4 conversions.
010: Perform and Accumulate 8 conversions.
011: Perform and Accumulate 16 conversions.
100: Perform and Accumulate 32 conversions.
101: Perform and Accumulate 64 conversions.
All remaining bit combinations are reserved.
