8. Tested initially and after any design or process changes that may affect these parameters, but not 100% tested.
9. Cypress uses constant current (ATE) load configurations and forcing functions. This figure is for reference only.
10. Input/output rise and fall time is measured between 0.8V and 2.0V.
