RFU

Reserved for future use. Do not change this register value.

DIS_SAFETY_TIMER

0: Enable

1: Disable

Disables both the Fast Charge and VBAT Low safety timers.

This also resets both safety timers. When this bit is set to 1, the

timers are held in reset (at 0). When this bit is written back to 0,

the timers start counting.

SUSPEND_SAFETY_TIMER

0: Counting

1: Suspend

If this is set to 1, both the Fast Charge and VBAT Low Safety

Timers stop counting and retain their current timer value. When

this bit is written back to 0, the counter resumes counting from

where it was suspended. If the counter is disabled during a

suspend condition using the DIS_SAFETY_TIMER bit, the

counter is reset to 0, even if suspended. It is then held at 0

until SUSPEND_SAFETY_TIMER is set to 0.

DIS_SAFTETY_TIMER reset has priority over

SUSPEND_SAFETY_TIMER.

FC_SAFETY_TIMER[4]

8 hours

Timer setting for the Fast Charge State only. When this timer

expires, Fast charging stops and sets the Timer Expired bit.
