CHRONTEL
M[2:0] = 4 or 5, OF = 1 (repeats pattern every line, CLKOUT = 27MHz)
Bits 1 through 3 of the MOF register along with ELFA, bit 6 select the mode that the IC operates according to the
table below. A listing of ‘FR’ in a column indicates that the frame rate is adjusted through varying this parameter,
and the table under the Frame Rate register should be used to determine this value. When modes 4 or 5 are selected,
the value of the FR register is ignored, and the IC will output a frame rate compatible with the field rate of PAL or
NTSC. An integer number of lines will be output in each frame, with the odd frames having one line more than the
even frames.
Bits 4, 5 and 7 ‘CHL’ ‘CVL’ ‘CIF2’ of the MOF register specify the chrominance sample location with respect to
the luminance samples in the horizontal and vertical directions respectfully. When CHL is 0, chrominance samples
are located between the luminance samples in the horizontal direction. When CHL is 1, chrominance samples are
aligned with alternate luminance samples. When CIF2 is 0 and CVL is 0, chrominance samples are located between
the luminance samples in the vertical direction. When CIF2 is 0 and CVL is 1, chrominance samples are aligned
with alternate luminance samples. When M[2:0] is set to mode 5, the CHL and CVL bits are ignored. When the
CIF2 bit is high, the CVL bit is ignored, and the chrominance signal is output on every line that has luminance.
