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.
