(10) Address data communication
There are two address data communication formats, namely, 7-bit addressing format and 10-bit ad-
dressing format. The respective address communication formats is described below.
To meet the 7-bit addressing format, set the 10BIT SAD bit of the I
7-bit address data transmitted from the master is compared with the high-order 7-bit slave address
stored in the I
of the I
format is selected, refer to Figure 2.11.45, (1) and (2).
To meet the 10-bit addressing format, set the 10BIT SAD bit of the I
address comparison is made between the first-byte address data transmitted from the master and the
7-bit slave address stored in the I
comparison between the RBW bit of the I
the address data transmitted from the master is made. In the 10-bit addressing mode, the R/W bit
which is the last bit of the address data not only specifies the direction of communication for control
data but also is processed as an address data bit.
When the first-byte address data matches the slave address, the AAS bit of the I
set to “1.” After the second-byte address data is stored into the I
address comparison between the second-byte data and the slave address by software. When the
address data of the 2nd bytes matches the slave address, set the RBW bit of the I
to “1” by software. This processing can match the 7-bit slave address and R/W data, which are re-
ceived after a RESTART condition is detected, with the value of the I
transmission format when the 10-bit addressing format is selected, refer to Figure 2.11.45, (3) and (4).
