NOTES
1_{The ADSP-2189M is 3.3 V tolerant (always accepts up to 3.6 Volt max VIH), but voltage compliance (on outputs, VOH) depends on the input VDDEXT; because VOH}
(max) ≈ V_DDEXT (max). This applies to Bidirectional pins (D0–D23, RFS0, RFS1, SCLK0, SCLK1, TFS0, TFS1, A1–A13, PF0–PF7) and Input Only pins (CLKIN,
RESET, BR, DR0, DR1, PWD).
