Example Programming
z Data Distribution Operation
The leftmost byte of D300 is 0, so DISTC(566) performs the Data Distribution Operation.
When CIO 0.00 is ON in the following example, the contents of D100 will be copied to D210 (D200 +
10) if the content of D300 is 0010 BCD. The content of D100 can be copied to other words by changing
the offset in D300.
z Stack Push Operation
The leftmost byte of Of is 9, so DISTC(566) performs the Stack Push Operation.
When CIO 0.00 is ON in the following example, DISTC(566) allocates a 10 word stack area (since the
rightmost 3 digits of Of are #010) between D200 and D209. At the same time, the contents of D100 will
be copied to the word calculated by adding D200 + stack pointer +1. Finally, the stack pointer is
incremented by +1.
Copied by DISTC(566).
