SIGNAL DESCRIPTIONS
The processors’ signal definitions are listed in
to maintain maximum function and reduce package size and
signal count, some signals have dual, multiplexed functions. In
cases where signal function is reconfigurable, the default state is
shown in plain text, while the alternate function is shown in
italics.
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. During hiber-
nate all outputs are three-stated unless otherwise noted in
Table
All I/O signals have their input buffers disabled with the excep-
tion of the signals noted in the data sheet that need pull-ups or
pull downs if unused.

7. In order
The SDA (serial data) and SCL (serial clock) pins/balls are open
drain and therefore require a pullup resistor. Consult version
2.1 of the I
It is strongly advised to use the available IBIS models to ensure
that a given board design meets overshoot/undershoot and sig-
nal integrity requirements. If no IBIS simulation is performed, it
is strongly recommended to add series resistor terminations for
all Driver Types A, C and D. The termination resistors should
be placed near the processor to reduce transients and improve
signal integrity. The resistance value, typically 33 Ω or 47 Ω,
should be chosen to match the average board trace impedance.
Additionally, adding a parallel termination to CLKOUT may
prove useful in further enhancing signal integrity. Be sure to
verify overshoot/undershoot and signal integrity specifications
on actual hardware.
