8.5 I
8.5.1 Introduction
The I
tween the microcontroller and the serial I
provides both multimaster and slave functions with
both 7-bit and 10-bit address modes; it controls all
I
timing and supports both standard (100KHz) and
fast I
Using DMA, data can be transferred with minimum
use of CPU time.
The peripheral uses two external lines to perform
the protocols: SDA, SCL.
