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.
Then a read/write operation is 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 has been 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 101 lists the various operations
under the control of the subaddress register for the control port.
SUB_USR_EN, Address 0x0E [5]
This bit splits the register map at Register 0x40.

Register Select (SR7 to SR0)
These bits are set up to point to the required starting address.
I C SEQUENCER
An I
2
C sequencer is used when a parameter exceeds eight bits
and is therefore distributed over two or more I
2
C registers, for
example, HSB [11:0].
When such a parameter is changed using two or more I
2
C write
operations, the parameter may hold an invalid value for the
time between the first I
2
C being completed and the last I
2
C
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
2
C sequencer holds the updated bits
of the parameter in local memory, and all bits of the parameter
are updated together once the last register write operation has
completed.
The correct operation of the I
2
C sequencer relies on the
following:
All I
2
C registers for the parameter in question must be
written to in order of ascending addresses. For example, for
HSB[10:0], write to Address 0x34 first, followed by 0x35,
and so on.
No other I
2
C can take place between the two (or more) I
2
C
writes for the sequence. For example, for HSB[10:0], write
to Address 0x34 first, immediately followed by 0x35, and
so on.
