RAM start address for the HD sync line count array; the byte following subaddress D0 points to the
first cell to be loaded with the next transmitted byte; succeeding cells are loaded by auto-incrementing
until stop condition. Each line count array entry consists of 2 bytes; see Table 90. The array has
15 entries.
HD line counter. The system will repeat the pattern described in ‘HLT’ HLC times and then start with
the next entry in line count array.
HD line type pointer. If not 0, the value points into the line type array, index HLT
description of the current line. 0 means the entry is not used.
RAM start address for the HD sync line type array; the byte following subaddress D1 points to the first
cell to be loaded with the next transmitted byte; succeeding cells are loaded by auto-incrementing
until stop condition. Each line type array entry consists of 4 bytes; see Table 92. The array has
15 entries.
HD line type; if not 0, the value points into the line pattern array. The index used is HLP
of value-duration pairs. Each entry consists of 8 pointers, used from index 0 to 7. The value 0 means
that the entry is not used.
RAM start address for the HD sync line pattern array; the byte following subaddress D2 points to the
first cell to be loaded with the next transmitted byte; succeeding cells are loaded by auto-incrementing
until stop condition. Each line pattern array entry consists of 4 value-duration pairs occupying 2 bytes;
see Table 94. The array has 7 entries.
HD pattern duration. The value defines the time in pixel clocks (HPD + 1) the corresponding value
HPV is added to the HD output signal. If 0, this entry will be skipped.
HD pattern value pointer. This gives the index in the HD value array containing the level to be inserted
into the HD output path. If the MSB of HPV is logic 1, the value will only be inserted into the Y/GREEN
channel of the HD data path, the other channels remain unchanged.
