8.2.2.1.1 DLPC200 Master, I2C Interface for EDID Programming

The DLPC200 controller I2C interface is only used to program the HDMI EDID. Upon plugging in an HDMI source, the DMD resolution is compared to the HDMI output resolution programmed in the HDMI EDID PROM. If the two resolutions do not match, then the HDMI EDID is adjusted to match the DMD resolution.

The bidirectional I2C bus consists of the serial clock (SCL) and serial data (SDA) lines. Both lines must be connected to a positive supply through a pullup resistor when connected to the output stages of a device. Data transfer may be initiated only when the bus is not busy.

I2C communication with this device is initiated by a master sending a Start condition, a high-to-low transition on the SDA input/output while the SCL input is high. After the Start condition, the device address byte is sent, MSB first, including the data direction bit (R/W).

After receiving the valid address byte, this device responds with an ACK, a low on the SDA input/output during the high of the ACK-related clock pulse.

On the I2C bus, only one data bit is transferred during each clock pulse. The data on the SDA line must remain stable during the high pulse of the clock period, as changes in the data line at this time are interpreted as control commands (Start or Stop). A Stop condition (a low-to-high transition on the SDA input/output while the SCL input is high) is sent by the master.

Any number of data bytes can be transferred from the transmitter to the receiver between the Start and Stop conditions. Each byte of eight bits is followed by one ACK bit. The transmitter must release the SDA line before the receiver can send an ACK bit. The device that acknowledges must pull down the SDA line during the ACK clock pulse so that the SDA line is stable low during the high pulse of the ACK-related clock period. Setup and hold times must be met to ensure proper operation.
