In this example, the value in A ($0:0124:FFFF) is larger than the expanded value in X0 ($0:0024:0000)
and the specified condition is true. The contents of the expanded X0 register are transferred to the
36-bit A accumulator, and the contents of the 24-bit R0 address register are transferred to the address
register R1. If the specified condition were false, a NOP instruction would be executed.
The condition codes are tested but not modified by this instruction.
