Generates 64-bit address (displacement) DISP64, adds it with content
of AGU accumulator register and replaces contents of the accumulator
with resulted value.
Note: DISP64 must be always expressed as a pair
"SYMBOL IMMEDIATE
".
Takes 2 cycles to execute.
Example: AGU_DA ZERO 5
DISP AGU
-------------
00000000 -
00000005 DA

AGU_DA ZERO 100
!! Generate 64-bit address (100)
!! add it with contents of AGU
!! accumulator register and load
!! it back to AGU accumulator.
