Circuit operation
(1) Command mode
With these ICs, commands are not recognized or acted upon until the start bit is received. The start bit is taken as
the first “1” that is received after the CS pin rises.

1 After setting of the read command and input of the SK clock, data corresponding to the specified address is output,
2 When the write or write all addresses command is executed, all data in the selected memory cell is erased
autematically, and the input data is writen to the cell.
3 These modes are optinal modes. Please contact Rohm for information on operation timing.
