Description
When the execution condition is OFF, ADBL(––) is not executed. When the
execution condition is ON, ADBL(––)) adds the eight-digit contents of Au+1 and
Au, the eight-digit contents of Ad+1 and Ad, and CY, and places the result in R
and R+1. CY will be set if the result is greater than FFFF FFFF.
