PIN DESCRIPTIONS
The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors pin
definitions are listed in Table 9. In order to maintain maximum
functionality and reduce package size and pin count, some pins
have dual, multiplexed functions. In cases where pin function is
reconfigurable, the default state is shown in plain text, while the
alternate function is shown in italics. Pins shown with an aster-
isk after their name (*) offer high source/high sink current
capabilities.
All pins are three-stated during and immediately after reset,
with the exception of the external memory interface, asynchro-
nous and synchronous memory control, and the buffered XTAL
output pin (CLKBUF). On the external memory interface, the
control and address lines are driven high, with the exception of
CLKOUT, which toggles at the system clock rate. If BR is active
(whether or not RESET is asserted), the memory pins are also
three-stated. During hibernate, all outputs are three-stated
unless otherwise noted in Table 9.
All I/O pins have their input buffers disabled with the exception
of the pins noted in the data sheet that need pull-ups or pull-
downs if unused.
The SDA (serial data) and SCL (serial clock) pins are open drain
and therefore require a pull-up resistor. Consult version 2.1 of
the I2C specification for the proper resistor value.
