Note
• Pins 9, 10, 13, 22 and 32 of connector EXP2 have source series termination resistors. These resistors
help to maintain the integrity of high-slew rate signals:
— Arm recommends pins 9, 10, 13 and 32 for use as clock outputs or sensitive data outputs in
preference to other pins.
— Arm recommends pin 22 of connector EXP2 for use as a clock input in preference to other pins.
