Examples 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.
Stack Push Operation
The leftmost byte of Of is 9, so DISTC(566) performs the Stack Push Opera-
tion.
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.
3-33-3 DATA COLLECT: COLLC(567)
Purpose Transfers the source word (calculated by adding an offset value to the base
address) to the destination word.
