NOTES:
5. AC tests performed with CL = 40pF, IOL = 5mA, and IOH = -5mA. Input reference level for FCLK and SCLK is 2.0V, all other inputs 1.5V. Test
VIH = 3.0V, VIHC = 4.0V, VIL = 0V.
6. Controlled via design or process parameters and not directly tested. Characterized upon initial design and after major process and/or changes.
