#92361 - maybe I solved the problem Responding to: ???'s previous message |
Thanks Oleg for your solution. But it cannot work. MOV PCON,#2 is the last command, which CPU can realize. I put JMP $ for any reason, but the routine stops after executing Power Down command. I tried your solution, and - I am sorry - it is not working.
After sending this message I tried to change the output value for P1, P2 and P3. Now my routine clears all bits of these ports (MOV P1-P2-P3, #0). And it seems to me, it is working. Maybe through output port my microcontroller is powering one of the peripheral chips (I mean through input), which is unpredictable when off. I don't know which, but now power consumption is really very low. Jacek |
