STRAP PIN FUNCTION DESCRIPTIONS
Some pins have alternate functions at reset. Strap options set
DSP operating modes. During reset, the DSP samples the strap
option pins. Strap pins have an approximately 100 k pull-
down for the default value. If a strap pin is not connected to an
external pull-up or logic load, the DSP samples the default value
during reset. If strap pins are connected to logic inputs, a stron-
ger external pull-down may be required to ensure default value

Reference voltage defines the trip point for all input buffers, except RESET, IRQ3–0, DMAR3–0,
ID2–0, CONTROLIMP2–0, TCK, TDI, TMS, and TRST. The value is 1.5 V ± 100 mV (which is the TTL
trip point). V
voltage divider should have an HF decoupling capacitor (1 nF HF SMD) connected to V
