Pins 13 – 16 are not available for use on the RF300 and should not be tied to any signals. These pins are used for
access to the onboard external memory.

GPIO16 has limited drive strength as it is routed through a 1Kohm resistor. The signal driven from (or to) GPIO16
can also be read, or driven, on pin 22 (CD2), the debug pin.
