In our application we use two MIBSPI Ports for communication with external device. MIBSPI3 is used for TX data and MIBSPI5 is used for RX data. Both ports are configured in Master mode, so MIBSPI3 uses SIMO[0] for TX and MIBSPI5 uses SOMI[0] for RX. TX is triggered using polling method. RX shall trigger an interrupt as soon as if 6 x 8bit data is received. The data looks proper on both lines (validated with an oscilloscope).
The issue at this point is that I only get a single interrupt after the first message. After that I see the correct data on the oscilloscope but no interrupt is triggered. What could be the problem here?
