(1) Minimum and maximum parameters are characterized for operation at T_A = 220°C unless otherwise noted, but may not be production
tested at that temperature. Production test limits with statistical guardbands are used to ensure high temperature performance.
(2) The following pins have no internal PU/PD: GPIOE0, GPIOE1, GPIOF0, GPIOF1, GPIOF2, GPIOF3, GPIOF12, GPIOG4, and GPIOG5.
(3) The following pins have an internal pulldown: XMP/MC, TESTSEL, and TRST.
