(3)
(a)
The SETRC instruction must be executed after executing the LDRS and LDRE instructions. In
addition, note that at least one instruction is required between the SETRC instruction and a repeat
start instruction.
(b)
If one of the following instructions is executed between an instruction following a repeat detection
instruction to a repeat end instruction, an illegal instruction exception occurs.
• Branch instructions
• Repeat control instructions
• Load instructions for SR, RS, and RE registers
Note: This restriction applies to all instructions for a repeat loop consisting of one to three
