1: enable horizontal Table Lookup
0: disable horizontal Table Lookup
RW 28H[0] Enable vertical Table Lookup (default 0)
1: enable vertical Table Lookup
0: disable vertical Table Lookup
RW 29H[4] Enable detection of short lines (IBM panel only,
default 0)
1: Enable such detection
0: disable such detection
RW 29H[3] OSD intensity selection
0: half intensity
1: full intensity
RW 29H[2] Should be kept low most time. A high pulse will
force SD1200 to reload all EEPROM entries
RW 29H[1] Should be kept low most time. A high pulse will
force SD1200 to reload mode dependent
EEPROM entries
RW 29H[0] External CPU control enable
0: disable external CPU control. SD1200 can write
control registers, but CPU only read control
registers.
1: enable external CPU control. CPU can
read/write control registers. SD1200 cannot write
control registers
R
2AH Read only internal status registers
1: indicate error status
0: indicate normal status
Bit 0: EEPROM vertical lookup table loading
Bit 1: EERPOM horizontal lookup table loading
Bit 2: EEPROM mode dependent entries loading
Bit 3: EEPROM calibration entries loading
Bit 4: input has too few lines
Bit 5: no input video
Bit 6: input data clock is too fast
Bit 7: refresh rate exceed LCD panel specification
R 2BH[3:0] Internal auto calibration state
