This TRX bit decides a transfer direction for data communication. When the TRX bit is set to “0”, receive
mode is entered and data is received from a transmit device. When the TRX bit is set to “1”, transmit
mode is entered, and address data and control data are output to the SDA
generated in the SCL
The TRX bit is set to “1” automatically in the following condition:
The TRX bit is set to “0” in one of the following conditions:
The MST bit selects either master mode or slave mode for data communication. When the MST bit is set
to "0", slave mode is entered and the START/STOP condition generated by a master device are received.
The data communication is synchronized with the clock generted by the master. When the MST bit is set
to "1", master mode is entered and the START/STOP condition is generated.
Additionally, clocks required for the data communication are generated on the SCL
The MST bit is set to “0” in one of the following conditions.

set to "0" (bus free), all the MST, TRX and BB flags are set to "1" at the same time. However, if the
BB flag is set to "1" immediately after the BB flag setting is confirmed because a START condition
is generated by other master device, the MST and TRX bits cannot be written. The duplicate
protect function is valid from the rising edge of the BB flag until slave address is received. Refer
to 16.9 START Condition Generation Method for details.
