6) Auto increment: This IC performs the designation of sub address by using the lower 5 bits. The uppermost bit is used for designation of auto increment. * When the sub address uppermost bit is defined as 0 (sub address: 00 to 19 HEX) The sequential data transfer leads to the sequential change of sub address, then the data is inputted.

The data is inputted as above. But the data will be invalid after sub address 1A. * When the sub address uppermost bit is defined as 1 or sub address is 80 to 99 HEX, the sequential data transfer leads to data input on the same address.
