Hi every one,

On a older application with the 18F25K20 I need some more I/O. So, I remove the crystal to get RA6 and RA7 available.

Now I want to switch to the internal osc and try this working with @_CONFIG_CONFIG1H_FOSC_INTIO67 but nothing happend.

OSCCON = % 01110000 ' set to 8MHz
OSCTUNE = % 00000000 ' set PLL off

For control I connect a LED to a I/O. When I put the crystal back, the LED is flashing...

The software is written in Pro 2.60C and MPASM is using.

In MicroCode Studio Plus the Device set to PIC18F25K20 and the compiler give no errors.
