(3) Replacing the COM instruction
If the COM instruction is used, add subroutine calls for P10 and P11 before and after the COM instruc-
tion. (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.
