(2) Data input (Sequence)
(a) Addresses are consists of 16 bits.
(b) Data is consists of 16 bits.
(c) Addresses and data are communicated in 8-bit units. Input the
lower 8 bits before the upper 8 bits. Make input from the MSB
side.
(d) After the start state has been attained and the control byte
(7CH) received, the next 16 bits (2 bytes) are for inputting the
address. Addresses are increased in increments for every 16
bits (2 bytes) of data input thereafter. As a result, it is not
necessary to input the address from the second data.
Note: During external synchronous, stop the external clock input
from the TCK pin while inputting data.
Fig. 14 Data input sequence
ACK* (Acknowledge) : Output the acknowledge signal whenever one byte input after the start state.
Output the acknowledge signal and recieve the data thereafter when mach the slave
address (7CH).
