Note:
16.2.3
SARX is an 8-bit readable/writable register that stores the second slave address and selects the
communication format. When the chip is in slave mode (and the addressing format is selected), if
the upper 7 bits of SARX match the upper 7 bits of the first frame received after a start condition,
the chip operates as the slave device specified by the master device. SARX is assigned to the same
address as ICDR, and can be written and read only when the ICE bit is cleared to 0 in ICCR.
SARX is initialized to H'01 by a reset and in hardware standby mode.
