Reset input
Crystal oscillator connection or external clock input.
Connect a crystal oscillator (16 MHz to 33 MHz), if used, to OSC0 and
OSC1_N.
Crystal oscillator connection.
Leave this pin unconnected if using external clock input.
Test pin. Drive at High level.
Debugging pin. Normally connect to ground.
Debugging pin. Normally leave open.

General-purpose port.
Not available for use as port pins when secondary functions are in use.
General-purpose port.
Not available for use as port pins when secondary functions are in use.
Note that enabling DRAM controller with MODE[2:0] inputs permanently
configures PIOB[15:9] for their secondary functions, making them
unavailable for use as port pins.
