matching address.

Figure 18. 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 pulls the SDA line low for one SCL clock cycle. A stop condition is initiated by the transmitting
device after the last byte is transferred. An example of a write cycle can be found in Figure 17. Note that the
TMDS461 does not allow multiple write transfers to occur. See Example – Writing to the TMDS461 section for
more information.
During a read cycle, the slave receiver acknowledges the initial address byte if it decodes the address as its
