Interface with CPU with Serial Port
When SK and DI are high at the rise of CE, high of DI is regarded as a start bit and the clock 1 generates and the high of DI is
fetched. When DI is low, DI is not regarded as a start bit until DI becomes high at the rise of SK.
After power on or after an instruction is performed, DI must be set 1 for preparing the fetch of the start bit of the next
instruction.
Figures 13 to 17 show the timings of write/read, and other operation modes, and interfacing examples are shown in Figures 18 to
20.
Figure 13 Read mode timing(S-24H45, S-24S45)
Figure 14 Read mode timing(S-24H30, S-24S30)
Figure 15 Write mode timing(S-24H45, S-24S45)
