Reserved—Must be undefined.
OVF—Overflow Status
0= An overflow did not occur in the digital filter for the current sample.
1= An overflow did occur in the digital filter for the current sample.
The ADC High Threshold register is used to set the trigger point above which an ADC
sample causes a CPU interrupt.
ADCTH—ADC High Threshold
These bits are compared to the most significant 8 bits of the single-ended ADC value. If
the ADC value exceeds this, an interrupt is asserted. The alarm function is not available in
DIFFERENTIAL mode.
The ADC Low Threshold register is used to set the trigger point below which an ADC
sample causes a CPU interrupt.
ADCTL—ADC Low Threshold
These bits are compared to the most significant 8 bits of the single-ended ADC value. If
the ADC value drops below this value an interrupt is asserted. The alarm function is not
available in DIFFERENTIAL mode.
