NAME	PROCESS VIRTUAL ADDRESS	WIDTH
NSTID	0x1FF80008	8
SYSCOREVER	0x1FF80010	4

MENUTID	0x1FF810A0	8
ACTIVEMENUTID	0x1FF810A8	8

All of these fields are initialized by the ARM11 kernel, except for MENUTID and ACTIVEMENUTID which are set by NS.

NSTID

This field contains the titleID of the first title to launch after the core system processes loaded. The PM module launches this title. If this field titleID is all-zero, the system will not attempt to launch the title. The regular ARM11 kernel sets this to the regular NS titleID, while the SAFE_MODE ARM11 kernel sets this to the SAFE_MODE NS titleID.

SYSCOREVER

When launching CXIs, the value stored here must match the core version field stored in the CXI exheader. If they do not match, the PM module will refuse to launch the ARM11 process. The regular ARM11 kernel sets this to 0x2, while the SAFE_MODE ARM11 kernel sets this to 0x3.

UNITINFO

Bit	Description
0	?
1	?
2	Set for debug units
3-7	?

Normally this register is all-zero, however bit2 in this register 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 register are clear.

MENUTID

This contains the titleID of the retail menu which will be launched by NS.

ACTIVEMENUTID

This contains the titleID of the currently running menu launched by NS. Normally this is the home menu TID from MENUTID, but if launching that fails this titleID is the alternate menu.(On debug units this is the TID loaded from config)
