mode, the slave address written in this register is compared with the address data to be received
immediately after the START condition are detected.
Not used when comparing addresses, in the 7-bit addressing mode. In the 10-bit addressing mode,
the first address data to be received is compared with the contents (SAD6 to SAD0 + RBW) of the I
address register.
The RBW bit is cleared to “0” automatically when the stop condition is detected.
These bits store slave addresses. Regardless of the 7-bit addressing mode and the 10-bit addressing
mode, the address data transmitted from the master is compared with the contents of these bits.
Bit 0: read/write bit (RBW)
Bits 1 to 7: slave address (SAD0–SAD6)
