REGISTER MAP
The master can write to or read from all of the registers except
the address pointer register, which is a write-only register. The
address pointer register determines which register the next read
or write operation accesses. All communications with the part
through the bus start with an access to the address pointer
register. After the part has been accessed over the bus and a
read/write operation is selected, the address pointer register is
set up. The address pointer register determines from or to which
register the operation takes place. A read/write operation is
performed from/to the target address, which then increments to
the next address until a stop command on the bus is performed.
