function or GPIO, the corresponding pin is held at low or high level respectively by the
internal logic.
Pins shared by EMI and FSMC: Depending on the AHB address to be accessed the pins are
used for EMI or FSMC transfers.

For the full description of the I/O functions related to each IP, please refer to the
corresponding sections of the SPEAR320 user manual.
PL_GPIO pin sharing for debug modes
In some cases the PL_GPIO pins may be used in different ways for debugging purposes.
There are three different cases (see also
