My english is not good enough to understand what You mean:
- You tryed accessing dataflash ? Can You show piececode with results? - That "memory map" is not very clear, yes, and probably is wrong (or semi-wrong ;-)) , but can be interpreted as follow: a) mov a,@r0 ; r0=1..255 - internal RAM movx a,@dptr ; dptr=256..65535 in total 64kB SRAM b) movx a,@r0 ; r0= 0..255 - dataflash. Did You tryed this? regards |
