When the execution condition is OFF, REGS(176) is not executed. When the ex-
ecution condition is ON, REGS(176) copies the data from data registers DR0,
DR1, and DR2 to D, D+1, and D+2, and copies the data from index registers IR0,
IR1, and IR2 to D+3, D+4, and D+5.
Refer to page 115 for general precautions on operand data areas.
Flags ER (A50003): Content of *DM word is not BCD when set for BCD.
Example When CIO 000000 is ON in the following example, the contents of words the
data and index registers is copied to D10000 through D10005.

5-29 STEP DEFINE and STEP START: STEP(008)/SNXT(009)
The step instructions STEP(008) and SNXT(009) are used in conjunction to set
up break points between sections in a large program so that the sections can be
executed as units and reset upon completion. A section of program will usually
be defined to correspond to an actual process in the application. (Refer to the
application examples later in this section.) A step is written like a normal pro-
gramming code, except that certain instructions (END(001), IL(002)/ILC(003),
JMP(004)/JME(005), and SBN(150)) may not be included.
The steps described here are not related to SFC programming.
