Bits
Description
4 Soft Reset
1: writing one causes a reset of the ADC block hardware (not the
registers)
0: writing zero takes the ADC block out of reset
3 Power_Saver_Dis
0: Power saving feature is enabled. The Analog to Digital Con-
verter controller powers down the ADC between conversion
sequences.
1: Power saving feature is disabled.

2 Start_Repeat
R/W
0: The ADC Repeat Mode is disabled. Note: This setting will not
terminate any conversion cycle in process, but will inhibit any fur-
ther periodic conversions.
1: The ADC Repeat Mode is enabled. This setting will start a con-
version cycle of all ADC channels enabled by bits Rpt_En[7:0] in
the ADC Repeat Register.
1 Start_Single
R/W
0: The ADC Single Mode is disabled.
1: The ADC Single Mode is enabled. This setting starts a single
conversion cycle of all ADC channels enabled by bits Sin-
gle_En[7:0] in the ADC Single Register.
Note: This bit is self-clearing
0 Activate
R/W
0: The ADC is disabled and placed in its lowest power state. Note:
Any conversion cycle in process will complete before the block is
shut down, so that the reading registers will contain valid data but
no new conversion cycles will begin.
1: ADC block is enabled for operation. Start_Single or Start_Re-
peat can begin data conversions by the ADC. Note: A reset pulse
is sent to the ADC core when this bit changes from 0 to 1.

38.11.2 ADC DELAY REGISTER
The ADC Delay register determines the delay from setting Start_Repeat in the ADC Control Register and the start of a
conversion cycle. This register also controls the interval between conversion cycles in repeat mode.
