Hi Shai,

Yes, you can use all the ADSP-BF523 Port H pins as GPIO. In default mode, all pins of Port H are in GPIO mode.

To enable Peripheral functionality, the Function Enable registers (PORTH_FER) must be explicitly written. Certain pins on Port H are multiplexed with more than one peripheral. In these cases, the required peripheral is controlled by the Multiplexer Control register (PORT_MUX).
