Type Aliases§

  • ADDR_R
    Field ADDR reader - Base address of the region.
  • ADDR_W
    Field ADDR writer - Base address of the region.
  • R
    Register MPU_RBAR reader
  • REGION_R
    Field REGION reader - On writes, specifies the number of the region whose base address to update provided VALID is set written as 1. On reads, returns bits [3:0] of MPU_RNR.
  • REGION_W
    Field REGION writer - On writes, specifies the number of the region whose base address to update provided VALID is set written as 1. On reads, returns bits [3:0] of MPU_RNR.
  • VALID_R
    Field VALID reader - On writes, indicates whether the write must update the base address of the region identified by the REGION field, updating the MPU_RNR to indicate this new region.
    Write:
    0 = MPU_RNR not changed, and the processor:
    Updates the base address for the region specified in the MPU_RNR.
    Ignores the value of the REGION field.
    1 = The processor:
    Updates the value of the MPU_RNR to the value of the REGION field.
    Updates the base address for the region specified in the REGION field.
    Always reads as zero.
  • VALID_W
    Field VALID writer - On writes, indicates whether the write must update the base address of the region identified by the REGION field, updating the MPU_RNR to indicate this new region.
    Write:
    0 = MPU_RNR not changed, and the processor:
    Updates the base address for the region specified in the MPU_RNR.
    Ignores the value of the REGION field.
    1 = The processor:
    Updates the value of the MPU_RNR to the value of the REGION field.
    Updates the base address for the region specified in the REGION field.
    Always reads as zero.
