#113997 - Finally, you are right! Responding to: Andy Neil's previous message |
Andy said:
The actual external access cycle is no quicker.
However, the code needed to set up the access is more compact (less to do - ony 1 address byte is used) and, therefore, quicker to execute. Yes, but you can do nearly the same, when only considering the low byte of DPTR. Ok, you have more addressing modes with Rn than with low byte of DPTR. And here you are right: Finally, coding will become more compact and application will run faster. Kai |
