HVS
DESCRIPTION
RAM start address for the HD sync value array; the byte following subaddress D3 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 2 bytes. The array has 8 entries.
HD pattern value entry. The HD path will insert a level of (HPV + 52) × 0.66 IRE into the data path.
The value is signed 8-bits wide; see Table 96.
HD horizontal sync. If the HD engine is active, this value will be provided at pin HSM_CSYNC;
see Table 96.
HD vertical sync. If the HD engine is active, this value will be provided at pin VSM; see Table 96.
