8-1. For STATUS signal timing information, refer to SECTION 12
TIONS INFORMATION.
The MC68030 provides the STATUS signal to identify instruction boundaries
a table search access for the logical address that caused the miss. Instruction-
and some exceptions. As shown in Table 8-2, STATUS indicates an instruction
boundary and exceptions to be processed, depending on the state of the
internal microsequencer. In addition, STATUS indicates when an MMU ad-
dress translation cache miss has occurred and the processor is about to begin
related exceptions do not cause the assertion of STATUS as shown in Table
