Bit 5—Master/Slave Select (MST)
Bit 4—Transmit/Receive Select (TRS)
MST selects whether the I
TRS selects whether the I
In master mode with the I
hardware, causing a transition to slave receive mode. In slave receive mode with the addressing
format (FS = 0 or FSX = 0), hardware automatically selects transmit or receive mode according to
the R/W bit in the first frame after a start condition.
Modification of the TRS bit during transfer is deferred until transfer of the frame containing the
acknowledge bit is completed, and the changeover is made after completion of the transfer.
MST and TRS select the operating mode as follows.
