ACCEPTABLE PRACTICE
GPIO
General-purpose input or output
Wake up I/O source should not be floating during hibernate.
All the I/O pins will float while in Hibernate and Reset
states. Ensure pullup and pulldown resistors are available
on board to maintain the state of the I/O.
Leave unused GPIOs as NC
No Connect
NC
20, 31, 33, 39,
41, 45
Unused pin, leave as NC.
SOP
Configuration sense-on-power
23, 24, 34
Leave as NC (Modules contain internal 100-kΩ pulldown
resistors on the SOP lines). An external 10-kΩ pullup resistor
is required to pull these pins high. See Section 5.11 for
SOP[2:0] configuration modes.
Reset
RESET input for the device
Never leave the reset pin floating
JTAG
