The routines that implement this work-around make an additional concession which is to disable interrupts during the IO sequence. Other hardware devices -(the LogicPD CPLD) have registers in the same the physical memory +(the LogicPD CPLD) have registers in the same physical memory region as the SMC chip. An interrupt might allow an access to one of those registers while SMC IO is being performed. |
