Table 112. Subaddress D0h
Data byte Description
HLCA
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 113. The array has 15 entries.
HLC
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.
HLT
HD line type pointer. If not 0, the value points into the line type array, index HLT − 1
with the description of the current line. 0 means the entry is not used.

Table 114. Subaddress D1h
Data byte Description
HLTA
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 115. The array has 15 entries.
HLP
HD line type; if not 0, the value points into the line pattern array. The index used is
HLP − 1. It consists 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.
