PIN DESCRIPTIONS
ADSP-BF539/ADSP-BF539F processor pin definitions are listed
in
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
Table 10. Pin Descriptions

exception of the pins that need pull-ups or pull-downs, as noted
in the table.
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.
