NOTES:
1. The data in front of the enable signal pulse will be latched.
2. The latched data will be repeated until there is an enable pulse.
3. The detected data will be updated with the next enable pulse.
4. After the R/W pin becomes INACTIVE, the data will be lost.
5. D1 corresponds to Clock1.
6. The enable and the SCK signals need to be set at the logic low level when the R/W signal changes.
7. The SCK must be held at low level when the enable signal is at high level.
