Operation:
Description: Clear the destination accumulator. This is a 56-bit clear instruction.
Example:
Explanation of Example: Prior to execution, the 56-bit A accumulator contains the
value $12:345678:9ABCDE. The execution of the CLR A instruction clears the 56-bit A
accumulator to zero.
Condition Codes:
S — Computed according to the definition in A.5 CONDITION CODE COMPUTATION
L — Set if data limiting has occurred during parallel move
E — Always cleared
U — Always set
N — Always cleared
Z— Always set
V — Always cleared
