External Clock
For applications where a clock is already available
elsewhere, users may directly drive the MCP2140 pro-
vided that this external clock source meets the AC/DC
timing requirements listed in
Section 4.3, “Timing Dia-
grams and Specifications”
.
Figure 2-2
shows how an
external clock circuit should be configured.

2.3.2
BIT CLOCK
The device crystal is used to derive the communication
bit clock (BITCLK). There are 16 BITCLKs for each bit
time. The BITCLKs are used for the generation of the
start bit and the eight data bits. The stop bit uses the
BITCLK when the data is transmitted (not for
reception).
This clock is a fixed-frequency and has minimal
variation in frequency (specified by the crystal
manufacturer).
