#157044 - DPTR to hold 16 bit address |
Is there some inclusive instruction I don't know about when writing to the DPTR.
To send a 16 bit address out serially I used the instruction MOV DPTR,#01FFH Then load DPH into the 8 bit serial engine and send it and finally DPL. Is something else being set or reset or modified inside the CPU when I use the DPTR this way? |

| No. It is just a register. | 01/01/70 00:00 | |
| Remember that there are two data pointers | 01/01/70 00:00 | |

Calm down - it's perfectly valid and correct | 01/01/70 00:00 | |
