Controls the security state of a peripheral request interface. Sampled by the DMA controller when it exits from reset.
These register bits should be updated during system initialization prior to removing the DMA controller from reset. They may not be changed dynamically during DMA operation.
Register Layout
Bits | Access | Reset | Description |
---|---|---|---|
[31:0] | RW | 0x0 | Peripheral Non-Secure |
Field : Peripheral Non-Secure - nonsecure | |
If bit index [x] is 0, the DMA controller assigns peripheral request interface x to the Secure state. If bit index [x] is 1, the DMA controller assigns peripheral request interface x to the Non-secure state. Reset by a cold or warm reset. Field Access Macros: | |

WARNING: The C register and register group struct declarations are provided for convenience and illustrative purposes. They should, however, be used with caution as the C language standard provides no guarantees about the alignment or atomicity of device memory accesses. The recommended practice for writing hardware drivers is to use the SoCAL access macros and alt_read_word() and alt_write_word() functions.
