REGISTER ACCESSES
The MPU can write to or read from all of the registers of the
ADV7304A/ADV7305A except the subaddress registers that are
write-only registers. The subaddress register determines which
register the next read or write operation accesses. All communica-
tions with the part through the bus start with an access to the
subaddress register. Then 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.
REGISTER PROGRAMMING
The following section describes the functionality of each regis-
ter. All registers can be read from as well as written to unless
otherwise 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 operation
is selected, the subaddress is set up. The Subaddress Register
determines to/from which register the operation takes place.
Register Select (SR7–SR0)
These bits are set up to point to the required starting address.
