Figure 35. Read command
By read command, data of EEPROM can be read. As for this command, set CS LOW, then input address after read ope
code. EEPROM starts data output of the designated address. Data output is started from SCK fall of 15 clock, and from
D7 to D0 sequentially. This IC has increment read function. After output of data for 1 byte (8bits), by continuing input of
SCK, data of the next address can be read. Increment read can read all the addresses of EEPROM. After reading data of
the most significant address, by continuing increment read, data of the most insignificant address is read.

Figure 36. Write command
By write command, data of EEPROM can be written. As for this command, set CS LOW, then input address and data
after write ope code. Then, by making CS HIGH, the EEPROM starts writing. The write time of EEPROM requires time
of tE/W (Max 5ms). During tE/W, other than status read command is not accepted. Start CS after taking the last data
(D0), and before the next SCK clock starts. At other timing, write command is not executed, and this write command is
cancelled. This IC has page write function, and after input of data for 1 byte (8 bits), by continuing data input without
starting CS , data up to 16 bytes can be written for one tE/W. In page write, the insignificant 4 bit of the designated
address is incremented internally at every time when data of 1 byte is input and data is written to respective addresses.
When data of the maximum bytes or higher is input, address rolls over, and previously input data is overwritten.
