PIC18F87J50 pin J7

[Jody]

Hello,
I want to use the pin J7 as a digital output.
But I think is is acting as /UB.
But in the CCS compiler I can't find the #FUSES to use this pin as digital output.
I see in the datasheet that is is possible...... but do I have to do something different??

Regards,
Jody

That's the 'mode'. Microcontroller/Extended microcontroller.
Look in the table 'fuses.txt' that comes with the complier.
MCU

also add:

setup_external_memory(EXTMEM_DISABLE);

to the code.

When 'extended mode' is selected, the external memory bus is always enabled (EMCU, or any of the other variants of this). With MCU, is becomes controllable by the EBDIS bit, which the setup_external_memory function controls.

Best Wishes

Thanks I got it working now!!
