8. Address Increment Timing

The address increment timing is as follows. See Figures 15 and 16. During reading operation, the memory

address counter is automatically incremented at the falling edge of the SCL clock (the 8th read data is

output).

During writing operation, the memory address counter is also automatically incremented at the falling

edge of the SCL clock when the 8th bit write data is fetched.
