This memory page is [[Memory_layout|read-only]] for ARM11 processes.
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 the low u8 from the NATIVE_FIRM titleID-low is larger than FIRMSYSCOREVER, [[AM:InstallNATIVEFIRM]] will trigger FIRM installing. When that u8 is not larger than FIRM_SYSCOREVER, and these two values don't match, [[AM:InstallNATIVEFIRM]] will return an error.

Bit1 in this field is set by the ARM11 kernel when ARM debug CP14 DSCR bit14 is set. [[NS]] loads the menu TID from MENUTID when bits 1-7 of this field are clear. [[ErrDisp]] will display development error info when bit0 is clear.

When this field is zero, bit0 for UNITINFO is set for retail. When this field is non-zero, bit0 for UNITINFO is clear for dev/debug units, and an ARM11 kernel state flag which enables debugging is set. Bit1 means JTAG connected.

The ARM11 loads the value of [[CONFIG_Registers#CFG_UNITINFO|CFG_UNITINFO]] from 0x1FFFFFF0+1 during startup, which is written by the ARM9 during ARM9<>ARM11 kernel sync.
When this field is zero, bit0 for ENVINFO is set for retail. When this field is non-zero, bit0 for ENVINFO is clear for dev/debug units, and an ARM11 kernel state flag which enables debugging is set. JTAG is only enabled for debugger and "firm" modes (bit1).

The ARM11 loads this value from 0x1FFFFFF0+2 during startup, which is written by the ARM9 during ARM9<>ARM11 kernel sync.
This originates from the low 8-bits of register [[CONFIG|0x10010000]]. When bit0 is set, the ARM11 kernel will not set the UPDATEFLAG to value 1.
