High-Band Operation
To operate in the high-band region, either the CIC field 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 13-14 on page 619.
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.
