REGISTER ACCESS
The MPU can write to or read from all of the ADV7180 registers
except the subaddress register, which is 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 or to the target address, which increments
to the next address until a stop command on the bus is performed.
REGISTER PROGRAMMING
The following sections describe the configuration for each
register. The communication register is an 8-bit, write-only
register. After the part is accessed over the bus 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. Table 105 lists the various operations under the
control of the subaddress register for the control port.

These bits are set up to point to the required starting address.
I
An I
and is therefore distributed over two or more I
example, HSB[10:0].
When such a parameter is changed using two or more I
operations, the parameter may hold an invalid value for the
time between the first I
being completed. In other words, the top bits of the parameter
may hold the new value while the remaining bits of the parameter
still hold the previous value.
To avoid this problem, the I
of the parameter in local memory, and all bits of the parameter
are updated together once the last register write operation has
completed.

HSB[10:0], write to Address 0x34 first, followed by 0x35,

Address 0x34 first, immediately followed by 0x35, and so on.
