Diagram Notes

All start and stop timing parameters apply to both read and write cycles.

Clock specifications are identical for read and write cycles. Write

timing parameters apply to slave address, word address, and write data

bits. Functional relationships are illustrated in the relevant datasheet

sections. These diagrams illustrate the timing parameters only.
