Re: m68k & Interrupts


To access C code from an interrupt context, all you'd have to do is:


.ISR:                              ; Interrupt service routine
	movem.l d0/d1/a0/a1,-(sp)  ; Save register not preserved across calls
	jsr     .C_ISR             ; call the C-based ISR
        movem.l (sp)+,d0/d1/a0/a1  ; Restore registers
	rte                        ; return from the ISR
