PHINC 1
TABLE 42. PHASE INCREMENT REGISTER 0
SUB ADDRESS = 6B_H
DESCRIPTION
The 8-bit registers PHINC 0–3 are cascaded together to form a 32-bit PHINC value. The
PHINC value is the phase increment value of the color subcarrier generation NCO. When the
BT.656 ancillary data is selected as the PHINC source, the PHINC registers may be read to
determine the last PHINC value loaded via the selected interface.
