2 The ADSP-218xN is 3.3 V tolerant (always accepts up to 3.6 V max VIH), but voltage compliance (on outputs, VOH) depends on the input VDDEXT, because VOH (max)
approximately equals VDDEXT (max). This 3.3 V tolerance applies to bidirectional pins (D23–D0, RFS0, RFS1, SCLK0, SCLK1, TFS0, TFS1, A13–A1, PF7–PF0) and input-
only pins (CLKIN, RESET, BR, DR0, DR1, PWD).
