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 data sheet sections.
These diagrams illustrate the timing parameters only.
