1.8.
C8051F330/1/2/3/4/5 devices include an on-chip voltage comparator that is enabled/disabled and config-
ured via user software. Port I/O pins may be configured as comparator inputs via a selection mux. Two
comparator outputs may be routed to a Port pin if desired: a latched output and/or an unlatched (asynchro-
nous) 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 1.15 shows the Comparator0 block diagram.
