pullup on E9, DSPIC33FJ256GP710A |

I'm trying to pull up pin E9 on a DSPIC33FJ256GP710A, but PIN_E9 is not defined in the h-file. What would the #define for that pin be?
Also, I'm using this as EXT2. Will the pullup work in this context?
Thanks |

I've been using this chip (DSPIC33FJ256GP710A). There is no E9 on it, PORTE only offers E0-E7.
EXT2 is tied to INT2, which is on pin A13, so you will have to use that for EXT2.
As far as I know, pullups on this chip are only available on pins with a CNx designation, where x is a number. You'll need to check the pin out to see which ones. |

Thanks. I was using the family datasheet. Turns out that the A at the end of the part number makes a pretty big difference!! |
