ADV7340/ADV7341
REGISTER MAP ACCESS
A microprocessor can read from or write to all registers of the
ADV7340/ADV7341 via the MPU port, except for registers that
are specified as read-only or write-only registers.
The subaddress register determines which register the next
read or write operation accesses. All communication through
the MPU port starts 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 the
transaction is complete.

REGISTER PROGRAMMING
Table 14 to Table 28 describe the functionality of each register.
All registers can be read from as well as written to, unless
otherwise stated.
SUBADDRESS REGISTER (SR7 TO SR0)
The subaddress register is an 8-bit write-only register. After the
MPU port is accessed and a read/write operation is selected, the
subaddress is set up. The subaddress register determines to or
from which register the operation takes place.
