(2) Data input (Sequence)
Note:During external synchronous , do not stop the external clock
Fig.24 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
(d) After the start state has been attained and the control byte
input from the TCK pin while inputting data.
the lower 8 bits before the upper 8 bits. Make input from
the MSB side.
(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.
