Hi Vasili,

The compiler seems to stop the processor when the program ends. During the forever loop the clkout pin shows a Fosc/4 signal, but when you exit the loop the clkout pin is quiet (and theĀ  the PWM signal stops also!).
Proof: at the end of the assembler code there is 'sleep' statement/loop.

Regards, Rob.

Hi Rob, I have understood some things:
1. Indeed the 12F1572_blink_intosc, with pragma target CLKOUTEN ENABLED returns Fosc/4 on RA4 pin only if forever loop end loop exists. If you expect to have that clock without any repetitive main program (comment the forever loop), it will not be there. It's possible to be a compiler issue, or a normal behavior of the microcontroller, I do not now.
