#186824 - Did you think about accesses using DATA1? Responding to: ???'s previous message |

Its not as simple as just changing the equates. Am i missing something obvious? You are probably missing that DATA1 is another EQU accessing P1 port pins. So code that uses DATA1 will not be compatible if you do change DB4, DB5, DB6, DB7. Another issue is how confusing it would be with DB4 being bit zero and DB7 being bit three. |
