ADCMCR controls ADC operation during low-power stop mode, background debug
mode, and freeze mode.
STOP places the ADC in low-power state. Setting STOP aborts any conversion in
progress. STOP is set to logic level one during reset, and may be cleared to logic level
zero by the CPU16. Clearing STOP enables normal ADC operation. However,
because analog circuitry bias current has been turned off, there is a period of recovery
before output stabilization.
The FRZ field determines ADC response to assertion of the FREEZE signal when the
device is placed in background debug mode. Refer to Table D–28.
This bit has no effect because the CPU16 always operates in supervisor mode.
Used for factory test only.
Port ADA is an input port that shares pins with the A/D converter inputs.
0 = Normal operation
1 = Low-power operation
