ADC data is continuously monitored by a programmable window detector, which interrupts the CPU when
data is within the user-programmed window. This allows the ADC to monitor key system voltages in back-
ground mode, without the use of CPU resources.

The MCU's have two on-chip voltage comparators. The inputs of the comparators are available at pack-
age pins as illustrated in Figure 1.11. Each comparator's hysteresis is software programmable via special
function registers (SFR's). Both voltage level and positive/negative going symmetry can be easily pro-
grammed by the user. Additionally, comparator interrupts can be implemented on either rising or falling-
edge output transitions. Please see 8.‘Comparators” on page 52 for details.
