Note 10. All digital pins except for DP, DN pins. Schmitt hysteresis level of RSTN pin and levels of all test pins are not
tested.
Note 11. EPAI, CKM, LMUTEN, RMUTEN, RSTN, XTE and TESTM0/1/2/3 pins.
Note 12. CSN, SK, EPAO, SUSN and CLKDRV pins.
Note 13. Expect for EPAI pin. EPAI pin has internal pull-down device, nominally 100kΩ.
