Appendix 4.12 CHK Instruction, IX Instruction
(1) CHK instruction
The CHK instruction operates as a fault check instruction for QnACPU.
For ACPU, there are two types of processing depending on the CPU type.
After conversion, program modification is required for each processing.
[For fault check]
Modify the CJ instruction in the step before the CHK instruction to a CHKST
instruction.
The CHK instruction pointer (P254) and the CJ instruction destination pointer
are converted to pointers with the same number. As the above pointers are
not used for QnACPU, delete them.
[For bit device output inversion]
The QnACPU has the FF instruction for inverting bit device outputs.
Modify the CHK instruction to the FF instruction.
(2) IX instruction
The IX instruction is converted, but not executed. Modify the program so that all the
devices that are objects of the IX instruction are subject to indexing.
• Fault check
AnCPU, AnNCPU (direct I/O control mode),
A3HCPU, AnACPU, AnUCPU
• Bit device output inversion
AnNCPU (refresh I/O control mode)
