8. Address increment timing
18
2-WIRE CMOS SERIAL E
S-24C04BPHAL
The address increment timing is as follows. During a read operation, the memory address counter is
automatically incremented at the falling edge of the SCL clock (where the 8th bit of read data is output).
During a write operation, the memory address counter is also automatically incremented at the falling edge of
the SCL clock when the 8th bit of write data is fetched.
