C8051F300/1/2/3/4/5 devices include an on-chip voltage comparator that is enabled/disabled and configured via user
software. All Port I/O pins may be configurated as comparator inputs. Two comparator outputs may be routed to a
Port pin if desired: a latched output and/or an unlatched (asynchronous) output. Comparator response time is pro-
grammable, allowing the user to select between high-speed and low-power modes. Positive and negative hysteresis is
also configurable.
Comparator interrupts may be generated on rising, falling, or both edges. When in IDLE mode, these interrupts may
be used as a “wake-up” source. The comparator may also be configured as a reset source.
