Receiving a Start-Bit
A start bit can be recognized by latching the high level of DI at the rising edge of SK after changing CS to high (Start-bit
Recognition). The write operation begins by inputting the write instruction and setting CS to low. The DO pin then outputs
low during the write operation and high at its completion by setting CS to high (Verify Operation). Therefore, only after a
write operation, in order to accept the next command by having CS go high, will the DO pin switch from a state of high-
impedence to a state of data output; but if it recognizes a start-bit, the DO pin returns to a state of high-impedence (see
Figure 3).
Three-wire Interface (DI-DO direct connection)
Although the normal configuration of a serial interface is a 4-wire interface to CS, SK, DI, and DO, a 3-wire interface is
also a possibility by connecting DI and DO. However, since there is a possibility that the DO output from the serial memory
IC will interfere with the data output from the CPU with a 3-wire interface, install a resistor between DI and DO in order to
give preference to data output from the CPU to DI(See Figure 12).
