5.4.
The ADC Programmable Window Detector continuously compares the ADC0 conversion results to user-
programmed limits, and notifies the system when a desired condition is detected. This is especially effec-
tive in an interrupt-driven system, saving code space and CPU bandwidth while delivering faster system
response times. The window detector interrupt flag (AD0WINT in register ADC0CN) can also be used in
polled mode. The ADC0 Greater-Than (ADC0GTH, ADC0GTL) and Less-Than (ADC0LTH, ADC0LTL)
registers hold the comparison values. The window detector flag can be programmed to indicate when mea-
sured data is inside or outside of the user-programmed limits, depending on the contents of the ADC0
Less-Than and ADC0 Greater-Than registers.
The Window Detector registers must be written with the same format (left/right justified, signed/unsigned)
as that of the current ADC configuration (left/right justified, single-ended/differential).
