15.6.3 Transferring a Data Word
INTSBIn interrupt
At the end of a data word transfer, the INTSBIn interrupt is generated to test <MST> to
determine whether the SBI is in the master or slave mode.
if MST = 0
Then
if TRX = 0
Then
if LRB = 0

Fig 15-15 <BC2:0> = “000” and <ACK> = “1” (Transmitter Mode)
Master mode (<MST> = “1”)
Test <TRX> to determine whether the SBI is configured as a transmitter or a receiver.
Transmitter mode (<TRX> = “1”)
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 eight bits, the data is written into SBInDBR. If the data has different
length, <BC2:0> and <ACK> are programmed and the transmit data is written into
SBInDBR. 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.
After the transfer is completed, the INTSBIn interrupt request is generated, <PIN> is set
to “0,” and the SCL pin is pulled to the “L” level. To transmit more data words, test <LRB> again
and repeat the above procedure.
