combination
Instruction below is not connected to bus line:
6617 STL, RET, MCR, P, I, DI, EI, FOR, NEXT, SRET, IRET, FEND
or END
STL, MC or MCR can be used only in main program, but it is
6618
used elsewhere (e.g. in interrupt routine or subroutine).
Invalid instruction is used in FOR-NEXT loop:
6619
STL, RET, MC, MCR, I (interrupt pointer) or IRET.

6621 Numbers of FOR and NEXT instructions 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.
Invalid instruction is programmed within STL-RET loop:
6626
MC, MCR, I (interrupt pointer), SRET or IRET.
6627 No STL instruction
Invalid instruction is used in main program:
6628
I (interrupt pointer), SRET or IRET
6629 No P or I (interrupt pointer)
No SRET or IRET instruction
6630
STL-RET or MC-MCR instructions in subroutine

Contents of error Action
This error occurs when a combination of instructions is
incorrect in the entire circuit block or when the relationship
between a pair of instructions is incorrect.
Modify the instructions in the program mode so that their
mutual relationship becomes correct.
