Appendix 5 Method of replacing High Performance model QCPU with Universal model QCPU
APPENDICES
(3) Replacing the COM instruction
If the COM instruction is used, add subroutine calls for P10 and P11 before and after
the COM instruction. (P10 and P11 are pointers shown in the program examples in
(2).) When SM775 is ON (Executes refresh set by SD778) and also the 0 bit of SD778
is OFF (Do not execute I/O refresh), replacement of the instruction is not necessary.
