16.3.3
SARX sets the second slave address and selects the communication format. In slave mode,
transmit/receive operations by the DTC are possible when the received address matches the
second slave address. If the LSI is in slave mode with the I
bit is set to 0 and the upper 7 bits of SARX match the upper 7 bits of the first frame received after
a start condition, the LSI operates as the slave device specified by the master device. SARX can be
accessed only when the ICE bit in ICCR is cleared to 0.
