High-Band Operation
To operate in the high-band region, either the CIC field or the CTC field in the ADCDCCTLn register
must be programmed to 0x3. This setting causes interrupts or triggers to be generated in the
high-band region according the operation mode. An example of the state of the interrupt/trigger
signal in the high-band region for each of the allowed operational modes is shown in Figure
12-16 on page 552. Note that a "0" in a column following the operational mode name (Always, Once,
Hysteresis Always, and Hysteresis Once) indicates that the interrupt or trigger signal is de-asserted
and a "1" indicates that the signal is asserted.
