UNLESS OTHERWISE NOTED, this document contains PRODUCTION DATA.
Transmission of all bits is MSB first and LSB last. Figure 10 shows the protocol without the acknowledge request (bit RFA = 0) and Figure 11 shows the protocol with the acknowledge request (bit RFA = 1).
Prior to both bytes, device address byte and data byte, one must apply a start condition. For this, pull the MODE/DATA pin high for at least tStart before the bit transmission starts with the falling edge. In case the MODE/DATA line was already at a high level (forced PWM mode selection), the device requires no application of a start condition prior to the device address byte.
Close the transmission of each byte with an end-of-stream condition for at least tEOS.
