Chapter 5: Standard RLL Instructions - Accumulator/Stack Load and Output Data
Pop (POP)
1
The Pop instruction moves the value from the first level
230
of the accumulator stack (32 bits) to the accumulator
240
and shifts each value in the stack up one level. In the
2
250-1
example below, when C0 is on, the value 4545 that was
on top of the stack is moved into the accumulator using the Pop instruction The value is
260
3
output to V2000 using the Out instruction. The next Pop moves the value 3792 into the
accumulator and outputs the value to V2001. The last Pop moves the value 7930 into the
DS Used
accumulator and outputs the value to V2002. Please note if the value in the stack were greater
4
HPP Used
than 16 bits (4 digits) the Out Double instruction would be used and two V-memory
locations for each Out Double must be allocated.
