ADV8005 Hardware Reference Manual
Function
hs_end_pos[9:0]
Description
0xXX
release hs when hcount reaches 0xXX
vs_h_beg_o_pos[10:0]
, IO Map,
Address 0x1B91[2:0]; Address 0x1B92[7:0]
This signal is used to specify the horizontal beginning position of VS for odd fields (counting from the EAV), if CEA 861 timing generation
is enable and manual values selected.
Function
vs_h_beg_o_pos[10:0]
Description
0xXX
assert vs when hcount reaches 0xXX on odd fields
vs_h_beg_e_pos[10:0]
, IO Map,
Address 0x1B93[7:0]; Address 0x1B94[7:5]
This signal is used to specify the horizontal beginning position of VS for even fields (counting from the EAV), if CEA 861 timing generation
is enable and manual values selected.
Function
vs_h_beg_e_pos[10:0]
Description
0xXX
assert vs when hcount reaches 0xXX on even fields
vs_v_beg_pos[5:0]
, IO Map,
Address 0x1B94[3:0]; Address 0x1B95[7:6]
This signal is used to specify the vertical beginning position of VS, if CEA 861 timing generation is enable and manual values selected.
Function
vs_v_beg_pos[5:0]
Description
0xXX
assert vs when lcount reaches 0xXX
vs_v_end_pos[5:0]
, IO Map,
Address 0x1B95[5:0]
This signal is used to specify the vertical ending position of VS, if CEA 861 timing generation is enable and manual values selected.
Function
vs_v_end_pos[5:0]
Description
0xXX
release vs when lcount reaches 0xXX
A worked example showing how 720 (1440) x 240p can be supported using manual AV-code configuration is shown in
. The horizontal
measurements must be the following:
= 276/2 = 138 = 0010001010
= 22 = 0010110
= 22 = 0010110
= 38/2 = 19 = 0000010011
= 4 = 000100
= 38/2 = 19 = 00000010011
= 7 = 000111
