deskthority

I would be interested in the pinout of the IC. With it I can measure the connections to the connector or testpoints.

I did measurements on the 2 Trackpoint boards. Now I am shure that the both ICs don't have the same pinout. But they have both 32 pins and the labeling is almost the same:

IC 1 ...

I found two trackpoints. I did some measurments to find the pinout. Please could some review if the following pinouts (of the ICs) are correct?

1st: IC = PTPM54DR
2 TX(DATA)
5 RESET ?
28 Clock
31 Button input 1
30 Button input 2
29 Button input 3

2nd: IC = PTPM54A DR
2 TX(DATA)
27 Clock
28 ...
