Controls the L3 master HPROT AHB-Lite signal.
These register bits should be updated only during system initialization prior to removing the peripheral from reset. They may not be changed dynamically during peripheral operation
All fields are reset by a cold or warm reset.

Field : hprot | |
Defines HPROT[4:1]. HPROT[0] from usb is tied HIGH to allow only data access. HPROT[4] Allocate 0: L3 master accesses for the module are non-allocatable 1: L3 master accesses for the module are allocatable HPROT[3] Cachable 0: L3 master accesses for the module are non-cacheable. 1: L3 master accesses for the module are cacheable. HPROT[2] Bufferable 0: L3 master accesses for the module are not bufferable. 1: L3 master accesses for the module are bufferable. HPROT[1] Privileged 0: L3 master accesses for the module are not privileged. 1: L3 master accesses for the module are privileged. 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.
