I’m designing a board that should be compatible with both SL808X and SL6087 devices.
There are several pins that have different assignement on the two models. The document “AirPrime_SL_Series_Migration_Guide_Rev4_0.pdf” shows these differences.
Just a question: the 808x has several pins that are declared as GND. (19, 20, 21, 23, 28, 30, 35, 37,38, 39, 52 ).
Some of them are used for different purposes on the SL6087:
19 = RTCK
20 = TRST
35 = Reserved
37 = GPIO
38 = GPIO
39 = GPIO
May I connect these pins to ground anyway? Or should I left them N.C. ?
