Bit 7..6 | CHARGE SAFETY TIMER VALUE0/1:
00 = safety timer times out after 4 hours 01 = safety timer times out after 5 hours 10 = safety timer times out after 6 hours 11 = safety timer times out after 8 hours |
Bit 5 | SAFETY TIMER ENABLE
0 = precharge timer, fast charge timer and taper timers are disabled 1 = precharge timer, fast charge timer and taper timers are enabled |
Bit 4 | SENSOR TYPE (NTC for battery temperature measurement)
0 = 100-kΩ curve 1 NTC 1 = 10-kΩ curve 2 NTC |
Bit 3 | CHARGER RESET:
0 = inactive 1 = Reset active. This Bit must be set and then reset through the serial interface to restart the charge algorithm |
Bit 2 | CHARGE TERMINATION ON/OFF:
0 = charge termination enabled, based on timers and termination current 1 = charge termination will not occur and the charger will always be on |
Bit 1 | SUSPEND CHARGE:
0 = Safety Timer and Precharge timers are not suspended 1 = Safety Timer and Precharge timers are suspended |
Bit 0 | CHARGER ENABLE
0 = charger is disabled 1 = charger is enabled; toggling the enable Bit will not reset the charger. Use CHARGER RESET Bit to reset charger. |
