1. If two I2C bus masters access the same device on the bus simultaneously, one using a read transaction and one using a write transaction, which CPU wins the arbitration? (Assume that the only difference in the first byte of the transaction is the R/W# bit.)

2. If two CAN bus masters access the bus, one with an 11-bit message ID of 0x4A0 and one with an 11-bit message ID of 0x3F2, which CPU wins the arbitration?
