	This is the WiFi MAC address for the 3DS. This is initialized by the [[NWM_Services\|NWM]] module~~, it~~'s ~~unknown where the MAC address written here was originally loaded from~~.		This is the WiFi MAC address for the 3DS. This is initialized by the [[NWM_Services\|NWM]] module and is loaded from the WiFi card's EEPROM.

	This memory page is [[Memory_layout\|read-only]] for ARM11 processes. This memory and the kernel code for it only exists under NATIVE_FIRM/SAFE_MODE_FIRM.		This memory page is mapped as "shared device" (it is thus uncached) and [[Memory_layout\|read-only]] for ARM11 processes. This memory and the kernel code for it only exists under NATIVE_FIRM/SAFE_MODE_FIRM.

	The FIRM_* fields are by default identical to the KERNEL_* fields. However, the FIRM_* fields can be overridden via FIRM-launch parameters, see [[FIRM\|here]].
