7.3.
The ADC Programmable Window Detector continuously compares the ADC2 output registers to user-pro-
grammed 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 system
response times. The window detector interrupt flag (AD2WINT in register ADC2CN) can also be used in
polled mode. The ADC2 Greater-Than (ADC2GTH, ADC2GTL) and Less-Than (ADC2LTH, ADC2LTL)
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 ADC2
Less-Than and ADC2 Greater-Than registers.
