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]].

Normally this is the same as SYSCOREVER. This used by [[AM:InstallNATIVEFIRM]] for comparing with the NATIVE_FIRM titleID-low.

When that u8 is not larger than FIRM_SYSCOREVER, and these two values don't match, [[AM:InstallNATIVEFIRM]] will return an error.

Bit[0] is set when the adapter is connected. Bit[1] is set when the battery is charging. Bit[2:4] is the value of [[PTM:GetBatteryLevel|battery level]]. If the connection bit is set but the charging bit is clear, it means the battery is already fully charged but still with adapter connected.
