TMS320F28335: SCI Communication.

Mark Philip Felipe

Part Number: TMS320F28335

Hi Team, seeking some clarification.

About SCI communication. I wanted to know that when the SCI gives an interrupt in idle line mode. I see that the SCI gives an interrupt after receiving like 2 bytes of data. However the TRM says that I should get an interrupt after address byte.

and this is the answer that I got from ti: About your inquiry, The serial communications interface is a 2-wire asynchronous serial port, commonly known as UART. The SCI contains a 16-level receive and transmit FIFO for reducing interrupt servicing overhead.

I am using 10 f28335 dsps that are communicating through sci

Thank you.

-Mark

    The timing of the interrupts depends on what interrupts are set. There is only one interrupt line per SCI, so any one of the various SCI interrupts can trigger the line. See the "SCI Port Interrupts" topic of the TRM for details on some of the interrupts available.
