Figure 25. I2C Acknowledge
Figure 26. I2C Address and Data Cycles
During a write cycle, the transmitting device must not drive the SDA signal line during the acknowledge cycle so
that the receiving device may drive the SDA signal low. After each byte transfer following the address byte, the
receiving device will pull the SDA line low for one SCL clock cycle. A stop condition will be initiated by the
transmitting device after the last byte is transferred. An example of a write cycle can be found in Figure 27 and
Figure 28. Note that the TMDS442 does not allow multiple write transfers to occur. See Example – Writing to the
TMDS442 section for more information.
During a read cycle, the slave receiver will acknowledge the initial address byte if it decodes the address as its
address. Following this initial acknowledge by the slave, the master device becomes a receiver and
