Although two ADD(30) can be used together to perform eight-digit BCD addi-
tion, ADDL(54) is designed specifically for this purpose.

When the execution condition is OFF, ADDL(54) is not executed. When the
execution condition is ON, ADDL(54) adds the contents of CY to the 8-digit
value in Au and Au+1 to the 8-digit value in Ad and Ad+1, and places the re-
sult in R and R+1. CY will be set if the result is greater than 99999999.
