Section 4 Exception Handling
SPC Saved by Exception in Repeat Control Period: 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.
Table 4.3
Note: The following labels are used here.
Illegal Instruction Exception in Repeat Control Period: If one of the following instructions is
executed at the address following RptDtct1, a general illegal instruction exception occurs. For
details on an address to be saved in the SPC, refer to the description in section 4.4.3, Exception in
Repeat Control Period.
• Branch instructions
• Repeat control instructions
• Load instructions for SR, RS, and RE

RptDtct2: An instruction address two instruction following the repeat detection instruction
RptDtct3: An instruction address three instruction following the repeat detection instruction

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 RC[11:0] is 1 or 0, a correct return
address is saved in the SPC.
