interrupt question

[chip15]

hi,
question: I have 2 codes for the interrupt to the INTERRUPT vector
04h, one on RBIE and the other on TOIE.
If during the execution of the program it occurs the second
interrupt, as ago the MCU to recognize which of the 2 codes it has
to perform?

THX
chip

MCU = 16f84a

ORG 04H


CODE 1..... (ON RBIE)


CODE 2......(ON TOIE)

----------------------------------------------------

MAIN PROGRAMM

Just test your interrupt flag bits in the int handler. These tell you which source generated the interrupt condition.

ORG 0x4

 ; save state if needed here

ISR
  btfss INTCON,T0IF ; if TMR0 interrupt, handle it 
  goto RB_INT       ; else skip to RB_INT

T0_INT
  ; CODE 2......(ON TOIE)
  bcf   INTCON,T0IF ; clear TMR0 int flag, and run handler

  ; insert your timer0 int handler here

RB_INT
  ; CODE 1..... (ON RBIE)
  bcf   INTCON,RBIF ; clear RB int flag, and run handler

  ; insert your RB int handler here

ISR_EXIT
  ; restore state if needed here

  retfie
