General-purpose I/O ports

PIOA[15:0]

General-purpose port.

I/O Not available for use as port pins when secondary functions are in use.

Primary Positive

PIOB[15:0]

General-purpose port.

Not available for use as port pins when secondary functions are in use. Note

I/O 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.
