I
next byte data receiving. In slave mode, the same function is available after it is addressed.
8.6 I
The following examples show programming for initialization, signalling START,
post-transfer software response, signalling STOP, and generating a repeated START.
8.6.1 Initialization Sequence
Before the interface can transfer serial data, registers must be initialized, as follows:
8.6.2 Generation of START
After completion of the initialization procedure, serial data can be transmitted by selecting
the master transmitter mode. On a multiple-master bus system, IBSR[IBB] must be tested
to determine whether the serial bus is free. If the bus is free (IBB = 0), the START signal
and the first byte (the slave address) can be sent. The data written to the data register
comprises the address of the desired slave and the lsb indicates the transfer direction.

C Programming Examples
1. Set IFDR[IC] to obtain SCL frequency from the system bus clock. See
2. Update the IADR to define its slave address.
3. Set I2CR[IEN] to enable the I
4. Modify the I2CR to select master/slave mode, transmit/receive mode, and
