We are using BF537 in our project ,
We configure the sport in unframed mode as follow:
*pSPORT1_TCR1 = 0; *pSPORT1_TCR1 = LTFS | ITFS | ITCLK; *pSPORT1_TCR2 = 3; *pSPORT1_TFSDIV =16; *pSPORT1_TCLKDIV = 4;
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?
