When the execution condition is OFF, MOVR(036) is not executed. When the
execution condition is ON, MOVR(036) copies the PC memory address of word
or bit S to the index register designated in D. The index register must be directly
addressed.
When S contains a timer or counter number, the PC memory bit address of the
timer or counter Completion Flag is copied to the index register. To access the
PC memory address of a timer or counter PV with an index register, move the PC
memory address of the timer or counter PV (#1000 or #1800) to an index register
with MOV(030)
If the index register contains a PC memory address for a timer/counter Comple-
tion Flag, a Transition Flag, or a Step Flag, the leftmost three digits indicate the
PC memory word address, and the rightmost digit indicates the bit.
Only direct addresses can be used for IR.
Content of *DM word is not BCD when set for BCD.
ER (A50003):
EQ (A50006): 0000 was placed in the index register.
The following example demonstrates the difference between MOV(030) and
MOVR(036). In the first instruction line, MOVR(036) copies the PC memory ad-
dress of CIO 0020 to IR0 when CIO 000000 is ON. In the second instruction line,
MOV(030) copies the content of CIO 0020 to IR0 when CIO 000000 is ON.
