The following signals are the bus exception control signals for the MC68030.
This bidirectional open-drain signa is used to initiate a system reset. An
external reset signal resets the MC68030 as well as all external devices. A

The halt signal indicates that the processor should suspend bus activity or,
when used with BERR, that the processor should retry the current cycle. Refer
