Mid-Band Operation
To operate in the mid-band region, either the CIC field or the CTC field in the ADCDCCTLn register
must be programmed to 0x1. This setting causes interrupts or triggers to be generated in the mid-band
region according the operation mode. Only the Always and Once operational modes are available
in the mid-band region. An example of the state of the interrupt/trigger signal in the mid-band region
for each of the allowed operational modes is shown in Figure 13-15 on page 636. Note that a "0" in
a column following the operational mode name (Always or Once) indicates that the interrupt or
trigger signal is de-asserted and a "1" indicates that the signal is asserted.
