MSP430F5326: I2C 9th cycle cycle not send by the MSP430F5326

Part Number: MSP430F5326


Hello,

I am using the MSP430F5326 and I would like to do as figure 36.3 of the datasheet:

Send the 7 bits adr + Write, expect the 9th clock cycle to read the ACK or NACK, have de processing delay and send the next byte according to ACK/NACK.

Unfortunetly, if I do not set the stop bit (UCB1CTL1 |= UCTXSTP; ) nor send the next byte ( UCB1TXBUF = *src++ ;) the MSP never sends the 9th clock cycle.

Do you have any idea about this issue?

Best regards

Mich
