REGISTER PROGRAMMING
This section describes the configuration of each register,
including the subaddress register, mode registers, subcarrier
frequency registers, the subcarrier phase register, timing
registers, closed captioning extended data registers, closed
captioning data registers, and NTSC pedestal control registers.
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.
Figure 37 shows the various operations under the control of the
subaddress register. Zero should always be written to SR7–SR6.
REGISTER SELECT (SR5–SR0)
These bits are set up to point to the required starting address.
