12.1. Comparator Multiplexers
C8051T610/1/2/3/4/5/6/7 devices include analog input multiplexers to connect Port I/O pins to the compar-
ator inputs. The Comparator0 inputs are selected in the CPT0MX register (SFR Definition 12.5). The
CMX0P1–CMX0P0 bits select the Comparator0 positive input; the CMX0N1–CMX0N0 bits select the
Comparator0 negative input. Likewise, the Comparator1 inputs are selected in the CPT1MX register (SFR
Definition 12.6). Important Note About Comparator Inputs: The Port pins selected as comparator inputs
should be configured as analog inputs in their associated Port configuration register, and configured to be
skipped by the Crossbar (for details on Port configuration, see Section “21.5. Special Function Registers
for Accessing and Configuring Port I/O” on page 124).
