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, SDTI, MGAIN1/2/3, CKM, LMUTEN, RMUTEN, RSTN, XTE and TESTM0/1/2/3 pins.
Note 12. CSN, SK, EPAO, SUSN, MCLK, LRCK, BICK, SDTO and CLKDRV pins.
Note 13. Expect for EPAI pin. EPAI pin has internal pull-down device, nominally 100kΩ.
