Master Receiver Mode
Figure 21-12. 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
ted. 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.
