6610
LD, LDI is continuously used 9 times or
more.
This error occurs when a
combination of instructions
is incorrect in the entire cir-
cuit block or when the rela-
tionship between a pair of
instructions is incorrect.
Modify the instructions in
the program mode so that
their mutual relationship
becomes correct.
6611
More ANB/ORB instructions than
LD/LDI instructions
6612
Less ANB/ORB instructions than
LD/LDI instructions
6613
MPS is continuously used 12 times or
more.
6614 No MPS instruction
6615 No MPP instruction
6616
No coil between MPS, MRD and MPP,
or incorrect combination
6617
Instruction below is not connected to
bus line: STL, RET, MCR, P, I, DI, EI,
FOR, NEXT, SRET, IRET, FEND or
END
6618
STL, MC or MCR can be used only in
main program, but it is used elsewhere
(e.g. in interrupt routine or subroutine).
6619
Invalid instruction is used in
FOR-NEXT loop: STL, RET, MC, MCR,
I (interrupt pointer) or IRET.
6620
FOR-NEXT instruction nesting level
exceeded
6621
Numbers of FOR and NEXT instruc-
tions do not match.
6622 No NEXT instruction
6623 No MC instruction
6624 No MCR instruction
6625
STL instruction is continuously used 9
times or more.
6626
Invalid instruction is programmed
within STL-RET loop: MC, MCR, I
(interrupt pointer), SRET or IRET.
6627 No RET instruction
6628
Invalid instruction is used in main pro-
gram: I (interrupt pointer), SRET or
IRET
6629 No P or I (interrupt pointer)
6630 No SRET or IRET instruction
6631 SRET programmed in invalid location
6632 FEND programmed in invalid location
