There is the option to force the FPD to power-down by calling the function
XPM_ForcePowerdown. This requires that the
requesting PU has proper privileges configured in the PMC. The PMC releases all PM
Slaves used by the APU automatically.
Important: This force method is
typically not recommended, especially when running complex operating systems on the APU
because it could result in loss of data or system corruption, due to the OS not
suspending itself gracefully.
For more information about XPM_ForcePowerdown, see
OS and
Libraries Document Collection (UG643).
