6 SEQUENCE INSTRUCTIONS
6.5 Master Control Instruction
Precautions
• If an instruction (e.g. LD, LDI) to be connected to the bus is not programmed following the MC instruction, a program
structure error (error code: 33E0) occurs.
• These instructions cannot be used in FOR to NEXT, STL to RETSTL, P to RET (SRET), and I to IRET. Also, do not block by
I, IRET, FEND, END, RET (SRET), RETSTL, etc. Addition by write during RUN mode results in an error.
• Nesting up to 15 levels (N0 to N14) is possible. When nesting instructions, the MC instruction is used starting from the
smallest (N) number and the MCR instruction is started starting from the biggest number. Programming in reverse order
does not produce a nested structure and hence the CPU module cannot execute operations properly.
• When the MCR instruction is nested at a single location, all master controls can be ended by just one nesting (N) number,
the smallest number.
