The only strange thing is that in Motorola's schematics says that
pins 3 and 5 of the Micrel 2025 are Not Connected and 4 is GND, and
Micrel's 2025 datasheet says that 3 is GND and 4 and 5 NC. Then, in
the Lite5200 GND pin 3 is connected to GND through an 1k resistor,
instead of directly as I suppose they pretended in the schematic, and
That is correct and an error in our Lite5200 layout. Thanks for the
feedback. We are replacing R164 with a 0 Ohm resistor. Our Total5200
platform does not share this problem.
