If an exception is accepted in the repeat control period while the repeat counter (RC[11:0]) in the
SR register is two or greater, the program counter to be saved may not indicate the value to be
returned correctly. To execute the repeat control after returning from an exception processing, the
return address must indicate an instruction prior to a repeat detection instruction. Accordingly, if
an exception is accepted in repeat control period, an exception other than re-execution type
exception by a repeat detection instruction cannot return to the repeat control correctly.

If a re-execution type exception is accepted at an instruction in the hatched areas above, a
return address to be saved in the SPC is incorrect. If SR.RC[11:0] is 1 or 0, a correct return
address is saved in the SPC.
