NOTE(S):
(1)
Denotes a register that is reprogrammed by the autoconfiguration process.
When sequentially writing a new register set to the CX25870/871, make sure to skip register 0xB8. This is the
autoconfiguration register and writing to it will overwrite registers 0x76 through 0xB4 and 0x38 with autoconfiguration values.
