Bit 2 (0x04) could be set when holding the power button for more than 5 seconds? (forced power off)
It is unknown whether it is set as the console powers off immediately.
Bit 7 (0x80) is unused?
Both bits are never used by the official ARM7 libraries, but could have some undocumented hardware functionality (?).
