Q.- When the Program counter points to the first location of external memory, WHAT address is output on the address lines? is it 0x0 ? or is it 0x2000 ?
A.- It is 0x2000. Q.- After 256 bytes (first 256 bytes accessed on-chip), the external data memory is accessed. What address would be output for the first address of external data memory? is it 0x0 or is it 0x100 ? A.- It is 0x0000. But using MOVX instructions!. Regards, Alfredo del Rio. |
