3 Bidirectional pins (DATA15–0, PF15–0, PG15–0, PH15–0, TFS0, TSCLK0, RSCLK0, RFS0, MDIO) and input pins (BR, ARDY, DR0PRI, DR0SEC, RTXI, TCK, TDI, TMS,
TRST, CLKIN, RESET, NMI, and BMODE2–0) of the ADSP-BF534/ADSP-BF536/ADSP-BF537 are 3.3 V-tolerant (always accept up to 3.6 V maximum VIH). Voltage
compliance (on outputs, VOH) is limited by the VDDEXT supply voltage.
