The NPI programming registers are accessed by the NPI host controller located in the PMC.
The NPI registers are addressable in the 32-MB memory space starting
at base address 0xF600_0000.
Access to the NPI host controller is protected by the NPI_XPPU protection unit in the PMC main switch. Burst accesses are supported to this address space.
Note: The NPI host
controller is located in the PMC.
The NPI-based registers are separate from the APB-based PMC and PS registers.
