Write to this register will abort current conversion sequence. READ: any
time, WRITE: any time.
WRITE: write to this register has no meaning. READ: Special Mode only.
ADPU — ATD Disable
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.
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.
