Register Description
1. Contrast Adjustment (8-Bits)
The Contrast adustment is made by controlling simultaneously the gain of three internal variable gain amplifiers
through the I
2
C bus interface.
The Contrast adjustment allows you to cover a typical range of 38 dB.
2. Sub Contrast Adjustments (8-Bits
3)
These Adustments are used to adjust the gain of each channel controlled by the I
2
C bus. The Sub Contrast
adjustment allows you to cover a typical range of 12 dB.

3. Brightness Adjustment (5-Bits)
The Brightness adjustment controls to add the same black level (pedestal) to the 3-channel R/G/B signals by
I
2
C bus.
4. Cut-Off Adjustments (8-Bits
3)
These Adjustments are used to adjust the white balance of the each channel controlled by the I
2
C bus.
5. Cut-Off Brightness Adjustment (8-Bits)
The Cut-Off Brightness Adjustment controls the 3-channel Cut-Off by I
2
C bus.
6. Slave Address
The 2-wire serial interface is an I
2
C BUS interface.
The Slave address of the S1D2504A01 is DCH (hexadecimal)
7. Data Transfer
All Bytes are sent MSB (Most Significant Bit) bit first and the write data transfer is closed by a STOP.
The MCU can write data into the S1D2504A01 registers.
To write data into the S1D2504A01, after a start, MCU must send :
- The I
2
C address slave byte with a low level for R/W bit (bit 1)
- The byte of the internal register address where the MCU wants to write data. (SUB Address)
- The Data sent to slave
- Stop
- 1-Byte Data Transfer
- Multi-Data Transfer
- Automatic increment
The automatic increment feature of the slave address enables a quick slave receiver initialization within one
transmission by the I
2
C BUS controller.
