W83627DHG

Publication Release Date: Aug, 22, 2007

-30- Version

1.4

7.2.2 I

C interface

This interface uses the I

C Serial Bus to access the internal registers. The W83627DHG has a

programmable serial-bus address that is controlled by index 48h.

The two timing diagrams below illustrate how to use the I

C interface to write to an internal register and

how to read the value in an internal register, respectively.

(a) Serial bus write to internal address register followed by the data byte
