ADA0M1 - ADC mode register 1

Preliminary User’s Manual U17566EE1V2UM00
If bit 0 is written, this is ignored.
Changing the ADA0FR3 to ADA0FR0 bits of the ADA0M1 register during
conversion (ADA0CE0 bit = 1) is prohibited.
When not using the A/D Converter, stop the operation by setting the
ADA0CE bit to 0 to reduce the current consumption.
The bit 7 must be changed to “1” after reset and must not be changed
afterwards.
Be sure to clear bits 5 and 4 to 0.
