NOTE:
can be performed. Note that powering up the module does not reset the
module since the register file is not initialized.
In power down mode, the control and result registers are still accessible.
IDLE mode for the ATD module is defined as the state where the ATD
module is powered up and ready to perform an A/D conversion, but not
actually performing a conversion at the present time. Access to all
control, status, and result registers is available. The module is
consuming near maximum power.
When not active, the sample-and-hold and analog-to-digital sub-
modules disable the clocks at their inputs to conserve power. The analog
electronics still draw quiescent current.
RUN mode for the ATD module is defined as the state where the ATD
module is powered up and currently performing an A/D conversion.
Complete assess to all control, status and result registers is available.
The module is consuming maximum power.
Asserting Stop causes the ATD module to power down. The digital clocks
are disabled and the analog quiescent current draw is turned off; this
places the module into its power down state and is equivalent to clearing
the ADPU control bit in ATDCTL2.
