We are using BF537  in our project ,

We configure the sport in unframed mode as follow:

*pSPORT1_TCR1 = 0;
*pSPORT1_TCR2 = 3;


in the TX interrupt ISR, we fill the transmit buffer with 16 words:after the sport transmit the 16 words, it will still transmit the last word written into the *pSPORT1_TX16 ,the receiver only expects the first 16 words .whether there is a method to stop the sport transmitting more data ?


BTW:the sport can not be disabled ,because the receiver need the clock of sport all time .


Any ideas on it?
