Field Line Count is the vertical parameter that holds the ideal number of lines per field for a given
video standard. It affects the way CP handles the unlocked state. If CP_LCOUNT_MAX[11:0] and
CH2_FR_FIELD_LENGTH[10:0] are set to 0, the internally used free run line length value is
decoded from the current setting of
For standards not covered by the preprogrammed values, the CP_LCOUNT_MAX[11:0],
CH2_FR_FIELD_LENGTH[10:0], and
expected number of lines per field.
Notes:
• The CP_LCOUNT_MAX[11:0] parameter has no effect on the video decoding.
• If neither CP_LCOUNT_MAX[11:0] nor CH2_FR_FIELD_LENGTH[10:0] are
programmed, then the Free-run Line Length parameter is decoded from
and VID_STD[5:0].
• If CP_LCOUNT_MAX[11:0] is programmed and CH2_FR_FIELD_LENGTH[10:0] is not,
the Free-run Line Length parameter defined by CP_LCOUNT_MAX[11:0] and
INTERLACED, is used for both channel 1 and channel 2.
• If CP_LCOUNT_MAX[11:0] is programmed and CH2_FR_FIELD_LENGTH[10:0] is also
programmed, the Free-run Line Length parameter defined by CP_LCOUNT_MAX[11:0]
and INTERLACED
CH2_FR_FIELD_LENGTH[10:0] is used for channel 2.
