** G = Ground

** A = Analog signal

The Internal connection column reports the name of the microprocessor signal, which in turn contains references to all the peripheral functions that can be associated to that pin. For example, the following pin name <code>CPU.VOUT[1]_B_CB_C[4]/EMAC[1]_MRXD[0]/VIN[1]A_D[1]/UART4_RXD/GP3[1]</code> means that the pin can be used as:
