Forum Post: RE: RX63T KPIT GNURX Compiler header file Problem

Hi, Thanks for your reply. I have check that when exception happen at that time PC is at void INT_Excep_BRK(void){  } in interrupt handler.c file. But At that time it should invoke reception interrupt, void  __attribute((interrupt)) Excep_SCI1_RXI1 (void) { g_sci_rx_buffer = (char)SCI1.RDR; DDI_transmitCharacter( g_sci_rx_buffer); } Yes. When I try to use receive interrupt it will jump to  void INT_Excep_BRK(void){  } in serial port. I want to use reception interrupt (Excep_SCI1_RXI1) in RX63T KPIT GNURX Compiler. Thank and Regards, Shail Shah
