When bit manipulation instructions are used to set MST and TRS in succession to specify
master transmit while operating in multi-master mode, an arbitration lost may occur, during
execution of the bit manipulation instruction to set TRS, with timing that results in a
contradictory state in which AL in ICSR is set to 1 and master transmit mode (MST = 1, TRS
= 1) is selected as well.
The following methods can be used to prevent this from occurring.
⎯ When operating in multi-master mode, always use the MOV instruction to set MST and
⎯ When an arbitration lost occurs, confirm that MST and TRS are both cleared to 0. If the
TRS.
settings are other than MST = 0, TRS = 0, clear MST and TRS to 0.
