Control Registers
The write packets must contain the address where the data must be written to and
the read packets must contain the address where the required data must be read.
The following figure shows the memory map for the writable and readable registers
on the SMT712.
The access to a specific register is made by reading or writing to the address:
Address from Host = Offset + Register Address
