Section 4 Instruction Features
There are several restrictions on repeat control:
1. At least one instruction must come between the SETRC instruction and the first instruction of
2. Execute the SETRC instruction after executing the LDRS and LDRE instructions.
3. When there are more than four instructions for the repeat program (loop) and there is no repeat
4. When there are three or fewer instructions in the loop, branch instructions (BRA, BSR, BT,

LDRS, LDRE), SR, RS, and RE load instructions, and TRAPA cannot be used. If they are
described, error exemption processing is started and the address values shown in table 4.33 are
pushed out to the stack area pointed by R15.
BT/S, BF/S, BSRF, RTS, BRAF, RTE, JSR, JMP), repeat control instructions (SETRC,
LDRS, LDRE), SR, RS, and RE load instructions, and TRAPA cannot be used for the last
three instructions in the repeat program (loop). If they are described, error exception
processing is started and the address values shown in table 4.34 are pushed out to the stack
area pointed by R15. In case of repeat control instruction (SETRC, LDRS, LDRE), and SR,
RS, and RE load instructions, they cannot be described in positions other than the repeat
module. If described, proper operation cannot be secured.
