2 _{All values need to be confirmed during device validation.}
3 _{Data based on characterization results, not tested in production}
4 _{Guaranteed by design simulation.}
5 _{This is a transient configuration during power-up, up to the end of reset PHASE2 (refer to RGM module section of the reference}
manual).
6 _{CL calculation should include device and package capacitance (CPKG < 5pF).}
