dsPIC33FJ I/O ports problems [solved]

I'm using a dsPIC33FJ128GP706 and I use several pins like outputs. Pins C15, G6, G7 and G8 not works ok.

I configure them with TRIS C and G these pins like outputs.

I try to put high with output high and writing directly in registers PORTC, LATC, PORTG and LATG but is not possible.

I have 4.120 version.

With 4.084 version pin C15 works ok but port G no.

Thanks

I've solved the problem.

Pin C15 not works because Fuses are wrong.

Pins G6-7-8 not works because with CCS SPI functions the SPI can't disable it. It's necessary to modify spi registers directly

Sorry
