ADSP-BF504/ADSP-BF504F/ADSP-BF506F
SIGNAL DESCRIPTIONS
Signal definitions for the ADSP-BF50x processors are listed in
Table 11. All pins for the ADC (ADSP-BF506F processor only)
are listed in Table 12.
In order to maintain maximum function and reduce package
size and pin count, some pins have multiple, multiplexed func-
tions. In cases where pin function is reconfigurable, the default
state is shown in plain text, while the alternate functions are
shown in italics.
During and immediately after reset, all processor signals (not
ADC signals) are three-stated with the following exceptions:
EXT_WAKE is driven high and XTAL is driven in conjunction
with CLKIN to create a crystal oscillator circuit. During
hibernate, all signals are three-stated with the following excep-
tions: EXT_WAKE is driven low and XTAL is driven to a solid
logic level.
During and immediately after reset, all I/O pins have their input
buffers disabled until enabled by user software with the excep-
tion of the pins that need pull-ups or pull-downs, as noted in
Table 11.
Adding a parallel termination to CLKOUT may prove useful in
further enhancing signal integrity. Be sure to verify over-
shoot/undershoot and signal integrity specifications on actual
hardware.
