| Battery flags. When zero the battery is at critical level, arm7 does a shutdown. Bit7 is set when the battery is charging. When the battery icon is full bars, low 4-bits are 0xF, and when the battery icon has one solid red bar left this is 0x3. When there's two bars in the battery icon this is 0x7, for three bars 0xb. 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.
