#120201 - you should exit the interrupt by reti.. Responding to: ???'s previous message |
...otherwise never get an another interrupt. This is the root cause.
Also, for some '51's it is recommended to have NOPs after the command which puts it into sleep, as the immediately following instruction tends to get skipped errorneously. Check out all the documentation for your processor, including the erratas. JW |
