Hello Steve,
Explain how you came up with the interpretation that Decrementing 0h means memory location zero. Could it possible mean the book was referencing an 8 bit value that when decremented would result in 0xFF? DEC can apply to A, R0-7 and internal Ram. If it were A, it would be DEC A, If it were a register it would be DEC Rx. SO this must be DEC (iram0) Unless you then say Iram 0 contains 0 to begin with, its state after DEC must be undefined. If you SO say its 0 then it will contain 255. Steve |
