set the STOPCn bit in USInCR4. 
Case 3: Master transmits repeated START condition with not checking ACK signal. In this 
case, load SLAn+R/W into the USInDR and set STARTCn bit in USInCR4. 
 
After doing one of the actions above, write any arbitrary to USInST2 to release SCLn line. 
For the case 1, move to step 7. For the case 2, move to step 9 to handle STOP interrupt. 
For  the  case  3,  move  to  step  6  after  transmitting  the  data  in  USInDR  and  if  transfer 

direction bit is ‘1’ go to master receiver section.

 

7.

 

1-Byte of data is being transmitted. During data transfer, bus arbitration continues. 

8.

 

This is ACK signal processing stage for data packet transmitted by master. I2C holds the 
SCLn  LOW.  When  I2C  loses  bus  mastership  while  transmitting  data  arbitrating  other 
masters, the MLOSTn bit in USInST2 is set. If then, I2C waits in idle state. When the data 
in USInDR is transmitted completely, I2C generates TENDn interrupt. 
 
I2C can choose one of the following cases regardless of the reception of ACK signal from 
slave: 
 
Case 1: Master receives ACK signal from slave, so continues data transfer because slave 
can receive more data from master. In this case, load data to transmit to USInDR. 
Case 2: Master stops data transfer even if it receives ACK signal from slave. In this case, 
set the STOPCn bit in USInCR4. 
Case 3: Master transmits repeated START condition with not checking ACK signal. In this 
case, load SLAn+R/W into the USInDR and set the STARTCn bit in USInCR4. 
 
After doing one of the actions above, write any arbitrary to USInST2 to release SCLn line. 
For the case 1, move to step 7. For the case 2, move to step 9 to handle STOP interrupt. 
For  the  case  3,  move  to  step  6  after  transmitting  the  data  in  USInDR,  and  if  transfer 

direction bit is ‘1’ go to master receiver section.

 

9.

 

This is the final step for master transmitter function of I2C, handling STOP interrupt. The 
STOP bit indicates that data transfer between master and slave is over. To clear USInST2, 
write any value to USInST2. After this, I2C enters idle state.
