I2C BUS Timing Requirement 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 I2C 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 I2C bus. The Sub Contrast adjustment allows you to cover a typical range of 12 dB. 13 I2C BUS COTROLLED R/G/B VIDEO AMPLIFIER S1D2504A01 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 I2C bus. 4. Cut-Off Adjustments (8-Bits × 3) These Adjustments are used to adjust the white balance of the each channel controlled by the I2C bus. 5. Cut-Off Brightness Adjustment (8-Bits) The Cut-Off Brightness Adjustment controls the 3-channel Cut-Off by I2C bus. 6. Slave Address The 2-wire serial interface is an I2C BUS interface. The Slave address of the S1D2504A01 is DCH (hexadecimal) Bit 8 Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 1 1 0 1 1 1 0 0 (W) 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 I2C 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.
