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. | ||
