| PIC24FV16KM204 regarding RA6 |

Hi All,
Compiler 5.010.
In the device file: 24FV16KM204.h, the data for PIN_A6 was missing.
Is there a reason why ccs left that port pin(RA6).
I added the line as below.
But the output would not toggle for PIN_A6.
Could someone please help.
Thanks and Regards,
Jai.
24FV16KM204.h

| Code: |
#define PIN_A0 5648
#define PIN_A1 5649
#define PIN_A2 5650
#define PIN_A3 5651
#define PIN_A4 5652
#define PIN_A5 5653
#define PIN_A6 5654 <--- this was added by me.
#define PIN_A7 5655
#define PIN_A8 5656
#define PIN_A9 5657
#define PIN_A10 5658
#define PIN_A11 5659

delay_ms(DELAY);
}

If you read the datasheet, you'll see that on the many versions of this processor family that pin is used for Vddcore/Vcap instead of RA6. In other words RA6 may not be usable on that processor.
