Bus Errors

The MCF548x has no bus monitor. If the auto-acknowledge feature is not enabled for the address that

generates the error, the bus cycle can be terminated by asserting TA or by using the software watchdog

timer. If it is required that the MCF548x handle a bus error differently, an interrupt handler can be invoked

by asserting an interrupt to the core along with TA when the bus error occurs.
