DESCRIPTION
data from input ports is encoded
colour bar with fixed colours is encoded
in slave mode, the encoder is only synchronized at the beginning of an odd field; default
after reset
in slave mode, the encoder receives a vertical sync signal
horizontal and vertical trigger is taken from FSVGC or both VSVGC and HSVGC; default
after reset
horizontal and vertical trigger is decoded out of “ITU-R BT.656” compatible data at PD port
Y-C_B-C_R to RGB dematrix is active; default after reset
Y-C_B-C_R to RGB dematrix is bypassed
pin HSM_CSYNC provides a horizontal sync for non-interlaced VGA components output
(at PIXCLK)
pin HSM_CSYNC provides a composite sync for interlaced components output (at XTAL
clock)
input luminance data is twos complement from PD input port
input luminance data is straight binary from PD input port; default after reset
input colour difference data is twos complement from PD input port
input colour difference data is straight binary from PD input port; default after reset

DESCRIPTION
video programming system data insertion is disabled; default after reset
video programming system data insertion in line 16 is enabled
pin VSM provides a LOW level if GPEN = 1
pin VSM provides a HIGH level if GPEN = 1
pin VSM provides a vertical sync for a monitor; default after reset
pin VSM provides a constant signal according to GPVAL
input data is sampled with inverse clock edges
input data is sampled with the clock edges specified in Tables 9 to 14; default after reset
normal assignment of the input data to the clock edge; default after reset
correct time misalignment due to inverted assignment of input data to the clock edge
