C8051F06x family of devices include three on-chip programmable voltage comparators, shown in
Figure 12.1. Each comparator offers programmable response time and hysteresis. When assigned to a
Port pin, the Comparator output may be configured as open drain or push-pull, and Comparator inputs
should be configured as analog inputs (see
Inputs” on page
“14.5. Comparator0 Reset” on page
The output of a Comparator can be polled by software, used as an interrupt source, used as a reset
source, and/or routed to a Port pin. Each comparator can be individually enabled and disabled (shutdown).
When disabled, the Comparator output (if assigned to a Port I/O pin via the Crossbar) defaults to the logic
low state, and its supply current falls to less than 1 µA. See
