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
effective in an interrupt-driven system, saving code space and CPU bandwidth while delivering faster sys-
tem 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).
