Revision B
1: enable horizontal rounding
0: disable horizontal rounding
RW 28H[2] Enable vertical rounding (default 0):
1: enable vertical rounding
0: disable vertical rounding
RW 28H[1] Enable horizontal Table Lookup (default 0):
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 of the time. A high pulse will
force SD1210 to reload all EEPROM entries
RW 29H[1] Should be kept low most of the time. A high pulse will
force SD1210 to reload mode dependent EEPROM
entries
RW 29H[0] External CPU control enable:
0: disable external CPU control. SD1210 can write
control registers, but CPU only read control registers.
1: enable external CPU control. CPU can read/write
control registers. SD1210 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
0: Idle State
1-4: Loading EEPROM data
5-9: Frequency Calibration State (Auto Frequency
Calibration will be done after state 9)
10: Phase Calibration State (Auto Phase Calibration
will be done after state 10)
11: Adjust Horizontal Back Porch state
12: Phase Tracking state
RW 2CH[7:0] Control Register A:
0 – disable
1 – enable
default is 00H
Bit 0: Horizontal Interpolation Offset Enable
