the AT1846 register map at at1846_registers.md appears to mismatch the AT1846S_programming_guide.pdf doc in few places like
missing 0x30[14] xtal_mode
missing 0x3A[14:12] voice_sel
mismatch values in 0x0A[5:0] pabias_voltage
missing 0x4C[15:0] instead have duplicate 0x4A
and few other inconsistencies.

I wonder which doc have the correct values? are they differs on purpose as being found experimentally to be different than documented?
@silseva any ideas?

Yes, the markdown page is misleading. I started writing it in an attempt of making some order between the AT1846S programming guide and the RDA1846S programming guide but I never finished it. The contents have been taken from the RDA1846S programming guide, whose registers' description is consistent with what we found in the GD-77 and MD-UV380 firmware.
