Protocol
Select the 9-bit UART mode for the master and slave controllers.
Set SC0MOD <WU> to “1” for the slave controllers to make them ready to receive data.
The master controller is to transmit a single frame of data that includes the slave controller
select code (8 bits). In this, the most significant bit (bit 8) <TB8> must be set to “1”.
Each slave controller receives the above data frame; if the code received matches with the
controller's own select code, it clears the WU bit to “0”.
The master controller transmits data to the designated slave controller (the controller of
which SC0MOD <WU> bit is cleared to “0”). In this, the most significant bit (bit 8) <TB8>
must be set to “0”.
The slave controllers with the <WU> bit set to “1” ignore the receive data because the most
significant bit (bit 8) <RB8> is set to “0” and thus no interrupt (INTRX0) is generated.
Also, the slave controller with the <WU> bit set to “0” can transmit data to the master
controller to inform that the data has been successfully received.
