Hi everybody, According to the manual, when a l.sys instruction in a delay slot is executed EPCR is loaded with address of corresponding jump instruction. However, this will result on an infinite loop, as the l.sys will be executed again. On a l.trap this is OK as traps are usually software breakpoints and the trap instruction will be removed by the service routine. Althought the routine servicing system calls could detect whether the l.sys was on a delay slot (by means of SR[DSX]), I think it will be better if EPCR was loaded with jump destination address in such cases. Please post your comments. Best regards, Carlos
