REGISTER DESCRIPTIONS
The master can write to or read from all of the
AD7745/AD7746 registers except the address pointer register,
which is a write-only register. The address pointer register de-
termines 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 to/from 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.
