Master Receiver Mode
Figure 6-89. Formats and States in the Master Transmitter Mode
In the Master Receiver mode, a number of data bytes are received from a Slave Transmitter
(Slave see
must be transmitted. The format of the following address packet determines whether Master
Transmitter or Master Receiver mode is to be entered. If SLA+W is transmitted, MT mode is
entered, if SLA+R is transmitted, MR mode is entered. All the status codes mentioned in this
section assume that the prescaler bits are zero or are masked to zero.
