Write the I2CMTPR register with the value of 0x0000.0009.
Specify the slave address of the master and that the next operation will be a Send by writing
the I2CMSA register with a value of 0x0000.0076. This sets the slave address to 0x3B.
Place data (byte) to be sent in the data register by writing the I2CMDR register with the desired
data.
Initiate a single byte send of the data from Master to Slave by writing the I2CMCS register with
a value of 0x0000.0007 (STOP, START, RUN).
Wait until the transmission completes by polling the I2CMCS register’s BUSBSY bit until it has
been cleared.
