The ATD control register 2 and 3 are used to select the power up
mode, interrupt control, and freeze control. Writes to these registers
abort any current conversion sequence.
Read or write anytime except ASCIF bit, which cannot be written.
Bit positions ATDCTL2[4:2] and ATDCTL3[7:2] are unused and
always read as zeros.
ADPU — ATD Disable
0 = Disables the ATD, including the analog section for reduction in
power consumption.
1 = Allows the ATD to function normally.
Software can disable the clock signal to the ATD converter and power
down the analog circuits to reduce power consumption. When reset
to zero, the ADPU bit aborts any conversion sequence in progress.
