| 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.

| This is used for [[MCURTC:SetInfoLEDPattern|controlling]] the notification LED (see [[MCURTC:SetInfoLEDPatternHeader]] as well), when this register is written. It's possible to write data here with size less than 0x64, and only that portion of the pattern data will get overwritten. Reading from this register only returns zeroes, so it's considered write-only.
