implement rx631 SCI ERI handler with GCC

honkytonky

Hi,

i have an UART running on the RX631 with GCC 

I have interrupt handlers for receive, transmit and transmit finished

INT_Excep_SCI5_RXI5
INT_Excep_SCI5_TXI5
INT_Excep_SCI5_TEI5

But according to the datasheet there is an ERI handler for errors like framing or parity which i can handle there.

I'm a little bit lost atm which interrupt vector i should use for this? my interrupt_handlers.h has no declaration for this vector


regards

    ok, i think i got it

    // enable ERI interrupt
IPR( ICU, GROUP12 ) = RS485_IP_LEVEL; // priority
IEN( ICU, GROUP12 ) = 1;
ICU.GEN[12].BIT.EN5 = 1; // enable RX err GROUP12 for 63x
// EN( SCI5, ERI5 );        // enable ERI5 error interrupt
the EN does to seem to do anything

this is my irq handler
this can be called by other SCIx aswell so maybe this needs better handling

void INT_Excep_ICU_GROUP12( void )
  {
    volatile uint8_t dummy = RS485_SCI.SSR.BYTE;
    RS485_SCI.SSR.BIT.FER  = 0;
    RS485_SCI.SSR.BIT.ORER = 0;
    RS485_SCI.SSR.BIT.PER  = 0;
  }
