ending point of burst in clock cycles
pin 19 is Real-Time Control Input (RTCI)
pin 19 is Sync Reset input (SRES)
LSB of the respective bytes are encoded immediately after run-in, the MSBs of the
respective bytes have to carry the CRCC bits, in accordance with the definition of copy
generation management system encoding format.
copy generation data output is disabled; default after reset
copy generation data output is enabled
DAC for BLUE output in 3-state mode (high-impedance)
DAC for BLUE output in normal operation mode; default after reset
DAC for GREEN output in 3-state mode (high-impedance)
DAC for GREEN output in normal operation mode; default after reset
DAC for RED output in 3-state mode (high-impedance)
DAC for RED output in normal operation mode; default after reset
DAC for CVBS output in 3-state mode (high-impedance)
DAC for CVBS output in normal operation mode; default after reset
RED output signal is switched to R DAC; default after reset
chrominance output signal is switched to R DAC
BLUE output signal is switched to B DAC; default after reset
CVBS output signal is switched to B DAC
if CSYNC = 0, CVBS output signal is switched to CVBS DAC; default after reset
if CSYNC = 0, luminance (VBS) output signal is switched to CVBS DAC
GREEN output signal is switched to G DAC; default after reset
luminance (VBS) output signal is switched to G DAC
