Table 5 indicates how I2C-bus register settings control the
colour and brightness. All colour registers are similar, they
contain one on/off bit, two brightness bits and three colour
type bits. To determine which colour is visible in the event
two or more colours being displayed on the same position,
the next priority scheme is followed:
1. Sub-select colour (SBS)
2. Sub-border colour (SB)
3. Main-select colour (MBS)
4. Main-border colour (MB)
5. Background colour (BG).
SA 15H AND SA 16H DECODER REGISTERS
The MVFILT and SVFILT bits can set the type of vertical
filtering. The MUVPOL and SUVPOL bits invert the UV
polarity of the incoming signals. The MVSPOL and
SVSPOL bits determine the active edge of the Vsync (see
Fig.7). The MHSYNC and SHSYNC bits determine the
timing of the Hsync pulse (burstkey or Hsync timing).
The MFPOL and SFPOL bits can invert the field
identification (ID) of the incoming fields (see Fig.7).
SA 17H DISPLAY SETTINGS REGISTER
The FBDEL bits can adjust the fast blank delay in 8 steps
of 1
2 a clock cycle (8 to +7). 0H is mid-scale.
The DUVPOL bit inverts the UV polarity of the border
colours.
The DVSPOL bit determines the active edge of the Vsync
(see Fig.7). The DHSYNC bit determines the timing of the
Hsync pulse (burstkey or Hsync). The DFPOL bit can invert
the field ID of the incoming fields (see Fig.7).
SA 18H PEDESTAL SETTINGS REGISTER
The PEDESTU and PEDESTV bits give the U and V DAC
outputs an offset of
8 to +7 LSB when the FBL is
switched off. This can be used to adjust the White point of
the system.
