ADI gives two examples for SPI Master. One with SPI1WritePacket and the other with SPI1ReadPacket.

Both use the SPI1_Int_Handler to transmit and recieve bytes by checking the SPI1STA register.

I dont get the ~CS rising edge (CSRSG) interrupt although was configured at  CSIRQ_EN bit8 of SPI1DIV register and continuous mode is enabled in CON bit11 of SPI1CON register

 

 

if((SPI1MSTATUS & 0x4000) == 0x4000)      // Rising edge detected on SPI Chip select pin

{

     I never get here

}

 

Any help appreceated
