ADX arg1, arg2
ADX takes the sum of
EX and stores it in
 Overflow handling
When the sum is too big, the overflow register
EX will be set to 0x0001. (There has been no word yet of whether an overflow of 0x0002 is possible.)
When the sum is manageable,
EX will be set to 0x0000
 Signing dependence
ADX handles both signed and unsigned numbers correctly. However, when operating on signed numbers, the overflow register
EX no longer indicates that carrying has occurred.
In binary machine code, this Basic opcode's five-bit representation is:
0b1 1010 (
The instruction has a takes three cycles to execute, plus any additional cycles necessary to evaluate the arguments.
