12.6.2 I
The I
address and a read/write bit. In the addressing mode, the slave ad-
dress written in this register is compared with the address data to be
received immediately after the START condition are detected.
(1) Bit 0: Read/Write Bit (RBW)
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.
(2) Bits 1 to 7: Slave Address (SAD0–SAD6)
These bits store slave addresses. Regardless of the 7-bit address-
ing mode and the 10-bit addressing mode, the address data trans-
mitted from the master is compared with the contents of these bits.
