| Writing u8 value 4 here triggers a hardware system reboot. Writing u8 value 1 (repeatedly) triggers a shutdown via power-off?
| System power control - bit0 = power off, bit1 = reboot (unused?). bit2 = reboot (used by mcu-module and LgyBg). bit3 = used by LgyBg to power off, causes hangs in 3DS-mode. bit4 = doesn't seem to do anything, but an mcu::RTC command uses this. Other bits are unused, and seem to do nothing.
