+When register 0x11 has value one written to, a power cycle is done. When reg 0x70 val 1 is written before reg 0x11, sysmenu/launcher doesn't display the heath screen, otherwise when not written with the register value left at zero the health screen is displayed. Reg 0x70 would be zero on hard boot, when any twlsdk app does a system reset it writes value 1 to reg 0x70.

+| Battery flags. When zero the battery is at critical level, arm7 does a shutdown. Bit7 is set when the battery is charging. Battery levels in the low 4-bits: battery icon bars full 0xF, 3 bars 0xB, 2 bars 0x7, one solid red bar 0x3, and one blinking red bar 0x1. When plugging in or removing recharge cord, this value increases/decreases between the real battery level and 0xF, thus the battery level while bit7 is set is useless.
