1.7.
C8051F41x devices include two software-configurable voltage comparators with an input multiplexer. Each
comparator offers programmable response time and hysteresis and two outputs that are optionally avail-
able at the Port pins: a synchronous “latched” output (CP0 and CP1), or an asynchronous “raw” output
(CP0A and CP1A). Comparator interrupts may be generated on rising, falling, or both edges. When in
IDLE or SUSPEND mode, these interrupts may be used as a “wake-up” source for the processor.
Comparator0 may also be configured as a reset source. A block diagram of the comparator is shown in
Figure 1.9.
