SAR is an 8-bit readable/writable register that stores the 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 SAR 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. SAR is assigned to the same
address as ICMR, and can be written and read only when the ICE bit is cleared to 0 in ICCR.
SAR is initialized to H'00 by a reset and in hardware standby mode.
Bits 7 to 1—Slave Address (SVA6 to SVA0): Set a unique address in bits SVA6 to SVA0,
differing from the addresses of other slave devices connected to the I
Bit 0—Format Select (FS): Used together with the FSX bit in SARX to select the communication
format.
• I
• Synchronous serial format: non-addressing format without acknowledge bit, for master mode
The FS bit also specifies whether or not SAR slave address recognition is performed in slave
mode.
