#158919 - write two different routines! Responding to: ???'s previous message |
In the 8051 architecture, SFRs are directly addressed only - it doesn't have any support for indirectly addressing an SFR (or an SFR bit, or any bit, for that matter).
Therefore you would have to implement the equivalent of an if-then-else construct. In my opinion, in a case like this, it probably isn't worth the effort - you might as well just have 2 separate routines. I'd say the same for 2 UARTs; probably even 4 - it's only when you get much above that that it becomes worth the effort of trying to write a "generic" driver... In my opinion. |
