1.10. Comparators
C8051F320/1 devices include two on-chip voltage comparators that are enabled/disabled and configured
via user software. Port I/O pins may be configured as comparator inputs via a selection mux. Two compar-
ator outputs may be routed to a Port pin if desired: a latched output and/or an unlatched (asynchronous)
output. Comparator response time is programmable, allowing the user to select between high-speed and
low-power modes. Positive and negative hysteresis are also configurable.
Comparator interrupts may be generated on rising, falling, or both edges. When in IDLE mode, these inter-
rupts may be used as a “wake-up” source. Comparator0 may also be configured as a reset source.
Figure 1.11 shows the Comparator0 block diagram.
