SYNCHRONIZATION OUTPUT SIGNALS
HS Configuration
The following controls allow the user to configure the behavior
of the HS output pin only:
Rev. B | Page 39 of 100
Beginning of HS signal via HSB[10:0]
End of HS signal via HSE[10:0]
Polarity of HS using PHS
The HS begin and HS end registers allow the user to freely
position the HS output (pin) within the video line. The values
in HSB[10:0] and HSE[10:0] are measured in pixel units from
the falling edge of HS. Using both values, the user can program
both the position and length of the HS output signal.
HSB[10:0] HS Begin, Address 0x34[6:4], Address
0x35[7:0]
The position of this edge is controlled by placing a binary
number into HSB[10:0]. The number applied offsets the edge
with respect to an internal counter that is reset to 0 immediately
after EAV Code FF, 00, 00, XY (see
205H
Figure 20). HSB is set to
00000000010b, which is 2 LLC1 clock cycles from Count[0].
The default value of HSB[10:0] is 0x002, indicating the HS pulse
starts two pixels after the falling edge of HS.
HSE[10:0] HS End, Address 0x34[2:0], Address 0x36[7:0]
The position of this edge is controlled by placing a binary
number into HSE[10:0]. The number applied offsets the edge
with respect to an internal counter that is reset to 0 immediately
after EAV Code FF, 00, 00, XY (see
206H
Figure 20). HSE is set to
00000000000b, which is 0 LLC1 clock cycles from Count[0].
The default value of HSE[9:0] is 000, indicating that the HS
pulse ends zero pixels after falling edge of HS.
For example:
1.
To shift the HS toward active video by 20 LLC1s, add
20 LLC1s to both HSB and HSE, that is, HSB[10:0] =
[00000010110], HSE[10:0] = 00000010100].
2.
To shift the HS away from active video by 20 LLC1s, add
1696 LLC1s to both HSB and HSE (for NTSC), that is,
HSB[10:0] = [11010100010], HSE[10:0] = [11010100000].
1696 is derived from the NTSC total number of pixels =
1716.
To move 20 LLC1s away from active video is equal to
subtracting 20 from 1716 and adding the result in binary to
both HSB[10:0] and HSE[10:0].
PHS Polarity HS, Address 0x37[7]
The polarity of the HS pin can be inverted using the PHS bit.
When PHS is 0 (default), HS is active high.
When PHS is 1, HS is active low.
