At this stage using the PMP function through harmony 8 of my pins as per the recommended layout of my LCD are directly connected to the micro, while the lower 8 data pins have a 10k PMP Read 58. My GUESS is that it might indicate the overflow and/or underflow bit is set in slave mode, but I could be totally wrong. For the PIC32 PMP it is most often used to drive displays. The videos are a complement to my book “Learn Harmony v3 for PIC32MZ Thanks for the offer to help. I was looking using the PIC32MX in a DIP package, so it could be bread-boarded.
