REGISTER ACCESSES
The MPU can write to or read from all of the registers of the
ADV7312 except the subaddress registers, which are write only
registers. The subaddress 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 subaddress
register. A read/write operation is then performed from/to the
target address, which increments to the next address until a stop
command is performed on the bus.

Register Programming
The following tables describe the functionality of each register.
All registers can be read from as well as written to, unless other-
wise stated.
Subaddress Register (SR7–SR0)
The communications register is an 8-bit write only register. After
the part has been accessed over the bus and a read/write opera-
tion is selected, the subaddress is set up. The subaddress register
determines to/from which register the operation takes place.
