C8051F300/1/2/3/4/5 devices include an on-chip programmable voltage comparator, which is shown in
Figure 7.1. Comparator0 offers programmable response time and hysteresis, an analog input multiplexer,
and two outputs that are optionally available at the Port pins: a synchronous “latched” output (CP0), or an
asynchronous “raw” output (CP0A). The asynchronous CP0A signal is available even when the system
clock is not active. This allows Comparator0 to operate and generate an output with the device in STOP
mode. When assigned to a Port pin, the Comparator0 output may be configured as open drain or push-pull
(see
source (see
The inputs for Comparator0 are selected in the CPT0MX register (SFR Definition 7.2). The CMX0P1-
CMX0P0 bits select the Comparator0 positive input; the CMX0N1-CMX0N0 bits select the Comparator0
negative input.
Important Note About Comparator Inputs: The Port pins selected as comparator inputs should be con-
figured as analog inputs in their associated Port configuration register, and configured to be skipped by the
Crossbar (for details on Port configuration, see
