#60338 - RE: P89C51RD2 and P87C51SBBB Responding to: ???'s previous message |
I had calculate that stack need to be 18 bytes !
IDATA 0071H 0001H UNIT ?STACK well (Hex) 71+18 = 89 and the P87C51 does not have RAM past 7f so the last 10 bytes on the 'stack' will be stored in thin air or overwrite your registers depending on chip design. Erik PS when are you goin to try a 87C52?????????? I see no reason to discuss this further before you try the advice given. Erik |
