| * (e.g. CSR_RESET_REG_FLAG_SW_RESET) or uCode-driven power-saving modes. |

| * Use iwl_write32() and iwl_read32() family to access these registers; |

| * Do not use iwl_write_direct32() family for these registers; |
| * no need to "grab nic access" via CSR_GP_CNTRL_REG_FLAG_MAC_ACCESS_REQ. |
| * The MAC (uCode processor, etc.) does not need to be powered up for accessing |
| * the CSR registers. |

| * NOTE: Device does need to be awake in order to read this memory |
| * via CSR_EEPROM and CSR_OTP registers |
