1 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).
2 Applies to output pins (BG, PWDACK, A0, DT0, DT1, CLKOUT).
ESD SENSITIVITY
CAUTION: ESD (electrostatic discharge) sensitive device. Electrostatic charges as high
as 4000V readily accumulate on the human body and test equipment and can discharge
without detection. Although the device features proprietary ESD protection circuitry,
permanent damage may occur on devices subjected to high-energy electrostatic dis-
charges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
