Data Transfer Procedure in the I2C Bus ModeI2C

11.6.3.1
SBI is in the master or slave mode.
INTSBIx interrupt
if MST = 0
Then go to the slave-mode processing.
if TRX = 0
Then go to the receiver-mode processing.
if LRB = 0
Then go to processing for generating the stop condition.

SBIxDBR
End of interrupt processing.
At the end of a data word transfer, the INTSBIx interrupt is generated to test <MST> to determine whether the

eight bits, the data is written into SBIxDBR. If the data has different length, <BC[2:0]> and <ACK>
are programmed and the transmit data is written into SBIxDBR.Writing the data makes <PIN> to "1",
causing the SCL pin to generate a serial clock for transferring a next data word, and the SDA pin to
transfer the data word.
and the SCL pin is pulled to the "Low" level.
Test <LRB>. If <LRB> is "1", that means the receiver requires no further data.
The master then generates the stop condition as described later to stop transmission.
If <LRB> is "0", that means the receiver requires further data.If the next data to be transmitted has
After the transfer is completed, the INTSBIx interrupt request is generated, <PIN> is cleared to "0",
To transmit more data words, test <LRB> again and repeat the above procedure.
