Figure 30. Subaddress Register
RE GIST E R ACCE SSE S
T he MPU can write to or read from all of the registers of the
ADV7175/ADV7176 except the subaddress register which is a
write only register. T he subaddress register determines which
register the next read or write operation accesses. All communi-
cations with the part through the bus start with an access to the
subaddress register. T hen 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.
RE GIST E R PROGRAMMING
T he following section describes each register, including
subaddress register, mode registers, subcarrier frequency regis-
ters, subcarrier phase register, timing registers, closed captioning
extended data registers, closed captioning data registers and
NT SC pedestal control registers in terms of its configuration.
Subaddress Register (SR7–SR0)
T he communications register is an eight bit write-only register.
After the part has been accessed over the bus and a read/write
operation is selected, the subaddress set up. T he subaddress
register determines to/from which register the operation takes
place.
Figure 30 shows the various operations under the control of the
subaddress register. Zero should always be written to SR7–
SR5.
Register Select (SR4–SR0):
T hese bits are setup to point to the required starting address.
MODE RE GIST E R 0 MR0 (MR07–MR00)
(Address (SR4–SR0) = 00H)
Mode Register 0 is a 8-bit wide register.
Figure 31 shows the various operations under the control of
Mode Register 0. T his register can be read from as well written to.
