REGISTER PROGRAMMING
The following section describes the functionality of each register.
All registers can be read from as well as written to.
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 operation
is selected, the subaddress is set up. The Subaddress Register
determines to/from which register the operation takes place.
Figure 15 shows the various operations under the control of the
Subaddress Register. “0” should always be written to SR7.
Register Select (SR6–SR0)
These bits are set up to point to the required starting address.

REGISTER ACCESS
The MPU can write to or read from all of the registers of the
ADV7202 except the Subaddress Registers, which are write-only.
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 then increments to the next address until a Stop
command on the bus is performed.
