PIC32MZ2048EFH144 I2C-3 Specific Question

As stated in the title i'm using a PIC32MZ2048EFH-144 Revision B2 silicon....
 
My question is there anything that would specifically inhibit or disable I2C-3?
 
I have no problems with I2C-1 and I2C-2 and with the B2 silicon i've run them at 400KHz without problems but
I2C-3 isn't working at all though I can toggle the pins (F2 and F8) using LATFbits and they work fine.
 
 
 

My configuration:
MacBook Pro (Retina, 15-inch, Mid 2015) with MacOS Mojave (10.14.6) and MPLAB X IDE v5.30
 
Curiosity PIC32MZ EF 1 & 2, PIC24F Curiosity, XPRESS EVAL BOARD (PIC16F18855), SAMA5D3 Xplained and various custom boards.

    Is that the revision where they cannabilised one of the higher I2C channels to fix the lower ones?
    If so, it would be documented in the errata.

    They did that on the A3 silicon and supposedly all of the I2C devices are working on the B2 silicon.

    Good luck. Sounds like you're the guinea pig!

    LOL... I kinda figured... but I did see a post where someone said they had all 3 I2C ports working on the B2 silicon.
     
    I got I2C-1 and -2 working, and briefly at 400KHz too, i'm just trying to figure out if it's something I did or a problem with my particular PIC32MZ.
     
    So i'm wondering if anyone else with the B2 silicon has had this problem too.

    My configuration:
    MacBook Pro (Retina, 15-inch, Mid 2015) with MacOS Mojave (10.14.6) and MPLAB X IDE v5.30
     
    Curiosity PIC32MZ EF 1 & 2, PIC24F Curiosity, XPRESS EVAL BOARD (PIC16F18855), SAMA5D3 Xplained and various custom boards.
