MMU Exception in Repeat Control Period: If an MMU exception occurs in the repeat control
period, a specific exception code is generated as well as a CPU address error. For a TLB miss
exception, TLB invalid exception, and initial page write exception, an exception code (H′070) is
specified in the EXPEVT. For a TLB protection exception, an exception code (H′0D0) is specified
in the EXPEVT. In a TLB miss exception, vector offset is specified as H′00000100.
An instruction where an exception occurs and the SPC value to be saved are the same as those for
the CPU address error.
After this exception processing, the repeat control cannot be returned correctly. To execute a
repeat loop correctly, care must be taken not to generate an MMU related exception in the repeat
control period.
Note: In a repeat loop consisting of one to three instructions, some restrictions apply to repeat

determined according to the SR before restore. An acceptance of other exceptions is
determined by processing mode of the SR after restore, and BL bit value. A processing-

address is executed. However, note that the correct operation cannot be guaranteed if a re-

or more instructions, restrictions apply to only the four instructions that include a repeat
end instruction. The restriction occurs when SR.RC[11:0] ≥ 1.
