(1) The Electrical Characteristics tables list ensured specifications under the listed Recommended Operating Conditions except as
otherwise modified or specified by the Electrical Characteristics conditions and/or notes. Typical specifications are estimations only and
are not ensured.
(2) Typical values represent most likely parametric norms at V_DD33 = 3.3 V, V_DDIO = 1.8 V or 3.3 V, T_A = +25°C, and at the Recommended
Operating Conditions at the time of product characterization and are not ensured.
(3) Specification is ensured by design and is not tested in production.
