#143902 - END is not an instruction Responding to: ???'s previous message |
After the NOP there will be no more code translated, so the program memory (ROM, FLASH) will contain FFs (=MOV R7,A) up to the end of internal ROM; and after that (if it is not the full 64kB), the behaviour is undefined.
If you want to "stop" execution at some point, either place there a STOP: SJMP STOP (yes, the good old "infinite" loop); or, if the hardware is fit to this, go to the powerdown mode (set bit 1 of PCON). JW PS. I added this as a FAQ, and also added a link to that FAQ into the "Common pittfalls" FAQ. |
