ADC0 Programmable Window Detector
The ADC0 Programmable Window Detector continuously compares the ADC0 output to user-programmed limits,
and notifies the system when an out-of-bound condition is detected. This is especially effective in an interrupt-driven
system, saving code space and CPU bandwidth while delivering faster system response times. The window detector
interrupt flag (AD0WINT in ADC0CN) can also be used in polled mode. The high and low bytes of the reference
words are loaded into the ADC0 Greater-Than and ADC0 Less-Than registers (ADC0GTH, ADC0GTL, ADC0LTH,
and ADC0LTL). Reference comparisons are shown starting on page 54. Notice that the window detector flag can be
asserted when the measured data is inside or outside the user-programmed limits, depending on the programming of
the ADC0GTx and ADC0LTx registers.
