*Sub address 2Fh(D5) 13.5M Trap
It can decrease the interference with 13.5MHz regarding to fh frequency and 14.3MHz regarding to fsc frequency.
0:OFF
1:ON (In this case, it needs to revise high frequency as below.)
(The relation resister)
Sub address 1Eh(D7-D2) Horizontal reference
When input signal is CVBS, it needs to shift 1 step. (000000→111111)
Sub address 04h(D1) Sharpness fo
Sub address 05h(D7-D6) Sharpness gain
If sharpness fo = 4.2MHz and sharpness gain = x1/8, the frequency characteristic is the same as trap-off.
*Sub address 22h、Sub23h、2Fh(D3) Regarding noise detection
22h(D7-D5) Horizontal start phase from under direction edge of H sync
22h(D4-D2) Horizontal width
23h(D7-D5) Vertical start phase
23h(D4-D2) Vertical line number select
【1-A】When sub address 2Fh (D3)=0, it is the start line number.
【1-B】When sub address 2Fh (D3)=1, it is the start line number.
