Hello All,
 
I am having some issues with my project and the Noise Error Flag, I seem to be getting this every other byte.  When I look at the signal with a scope I the signal looks clean. 
 
I notice in the databook for the MC9S08AWxx family it says the Noise error interrupt can be disabled.  I am using CW 6.0 and I used the Async Bean to setup my serial port.  I don't see specific controls for enabling\disabling specific error flags.  Does anyone know how this can be done without stepping on the generated code?  Or am I going to have to do something manually?
 
Thanks,
Dave

Hello,
I'm sorry, but currently there's not possible to disable the Noise Error interrupt. The only possibility is to disable a generation of the module (using the pop-up menu of the bean) and modify the code manually.
Anyway, I recommend to check if your signals have correct levels and timing, because there probably is some reason for invoking this error interrupt....
