Controller receiver mode can be entered only from controller transmitter mode. With any of the address formats (a), (b), or (c) (see Figure 12-120), if R/W_ is high, the module enters controller receiver mode after the target address byte and bit R/W_ are transmitted. Serial data bits received on bus line SDA are shifted in synchronization with the self-generated clock pulses on SCL.
