SAD6-SAD0 (Slave Address) (b7-b1)
Bits SAD6 to SAD0 indicate a slave address to be compared for a slave address match detection in
slave mode. An I²C interface can have maximum of three slave addresses. Set bits SAD6 to SAD0 in
the S0Di register to 0000000b when not setting the slave address.
However, when the MSLAD bit in the S4D0 register is 0, registers S0D1 and S0D2 are disabled. Only
the slave address set to the S0D0 register is compared with address data received.
