You can find the circuit diagram and pin diagram of the BM1387 chip in the S9 hashboard repair manual. However, no information about the register map. Or as BitMaxz said, contact Skot as he was also looking for this information.

No one yet shares a datasheet for BM1387 here on the forum but Skot might be able to help you because he is developing bitaxe with BM1387 chip.
You can also check this post below you might get some information that you need about this chip.

I need the pinouts and possibly the datasheets for BM1387 and also the register map, is there anyone out there who's willing to help?
