Receiving a Start-Bit
Both the recognition of a start-bit and the VERIFY procedure occur when CS is " high ". 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.
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 28).
