9.12.1 Initialization
9.12 I
This section provides examples of operations that must be performed by various I
service routines. This includes:
In the initialization example, the I
For each mode, a buffer is used for transmission and reception. The initialization routine
performs the following functions:

Initialization of the I
I
The 26 state service routines providing support for all four I
I2ADR is loaded with the part’s own slave address and the general call bit (GC).
The I
The slave mode is enabled by simultaneously setting the I2EN and AA bits in I2CON
and the serial clock frequency (for master modes) is defined by loading CR0 and CR1
in I2CON. The master routines must be started in the main program.
