PIN DESCRIPTIONS
ADSP-BF531/2/3 processor pin definitions are listed in
Table 9
.
All pins are three-stated during and immediately after reset,
except the Memory Interface, Asynchronous Memory Control,
and Synchronous Memory Control pins, which are driven high.
If BR is active, then the memory pins are also three-stated. All
unused I/O pins have their input buffers disabled with the
exception of the pins that need pullups or pulldowns as noted in
the table footnotes.
In order to maintain maximum functionality and reduce pack-
age size and pin count, some pins have dual, multiplexed
functionality. In cases where pin functionality is reconfigurable,
the default state is shown in plain text, while alternate function-
ality is shown in italics.
