REGISTER PROGRAMMING
MODE REGISTER 0 MR0 (MR07 TO MR00)
This section describes each register, including subaddress
register, mode registers, subcarrier frequency registers,
subcarrier phase register, timing registers, closed captioning
extended data registers, closed captioning data registers, and
NTSC pedestal control registers, in terms of its configuration.
(Address [SR4 to SR0] = 00H)
Figure 38 shows the various operations under the control of
Mode Register 0. This register can be read from as well as
written to.
SUBADDRESS REGISTER (SR7 TO SR0)
MR0 BIT DESCRIPTION
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.
Output Video Standard Selection (MR01 to MR00)
These bits are used to set up the encode mode. The ADV7170/
ADV7171 can be set up to output NTSC, PAL B/D/G/H/I, and
PAL M/N standard video.
Luminance Filter Control (MR02 to MR04)
Figure 37 shows the various operations under the control of the
subaddress register. Zero should always be written to SR7 to SR6.
These bits specify which luma filter is to be selected. The filter
selection is made independent of whether PAL or NTSC is
selected.
REGISTER SELECT (SR5 TO SR0)
These bits are set up to point to the required starting address.
Chrominance Filter Control (MR05 to MR07)
These bits select the chrominance filter. A low-pass filter can be
selected with a choice of cutoff frequencies, 0.65 MHz,
1.0 MHz, 1.3 MHz, or 2 MHz, along with a choice of CIF
or QCIF filters.
