12. Comparator0 and Comparator1
C8051T610/1/2/3/4/5/6/7 devices include two on-chip programmable voltage comparators: Comparator0 is
shown in Figure 12.1, Comparator1 is shown in Figure 12.2. The two comparators operate identically with
the following exceptions: (1) Their input selections differ as described in Section “12.1. Comparator Multi-
plexers” on page 65; (2) Comparator0 can be used as a reset source.
The Comparators offer 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 CP1), or an
asynchronous “raw” output (CP0A or CP1A). The asynchronous signals are available even when the sys-
tem clock is not active. This allows the Comparators to operate and generate an output with the device in
STOP mode. When assigned to a Port pin, the Comparator outputs may be configured as open drain or
push-pull (see Section “21.4. Port I/O Initialization” on page 121). Comparator0 may also be used as a
reset source (see Section “19.5. Comparator0 Reset” on page 104).
The Comparator inputs are selected by the comparator input multiplexers, as detailed in Section
“12.1. Comparator Multiplexers” on page 65.
