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 internal pullup or pulldown for
the default value. If a strap pin is not connected to an overdriv-
ing external pullup, pulldown, or logic load, the DSP samples
the default value during reset. If strap pins are connected to
logic inputs, a stronger external pullup or pulldown may be
required to ensure default value depending on leakage and/or
low level input current of the logic load. To set a mode other
than the default mode, connect the strap pin to a sufficiently
stronger external pullup or pulldown.
Table 15
lists and
describes each of the DSP’s strap pins.
