How master McBsp knows slave McBsp has received all the transmitted data

Hi all,

I have two 28069 DSPs. One uses McBsp as a master to send the data to the slave Mcbps on another DSP. I know transmit ready register on the master DSP will tell you when the transmission has completed. Is there any register on the master DSP which can read some slave McBsp pin to decide the slave has received all the data?

Thanks

  • Fei,

    There is no such feature to determine whether the slave has received the data. If you are using full duplex communication and also have enough time for one extra word. The Master could send a dummy word to the slave and the slave could reply back notifying the master that it has received data.
