The STATUS register provides information about the current state of the bq29330.
STATUS b0 (SCD): This bit indicates a short circuit in discharge condition.
0 = Voltage below the short circuit in discharge threshold (default).
1 = Voltage greater than or equal to the short circuit in discharge threshold.
STATUS b1 (SCC): This bit indicates a short circuit in charge condition in the charge direction.
0 = Voltage below the short circuit in charge threshold (default).
1 = Voltage greater than or equal to the short circuit in charge threshold.
STATUS b2 (OL): This bit indicates an overload condition.
0 = Voltage less than or equal to the overload threshold (default).
1 = Voltage greater than overload threshold.
STATUS b3 (WDF): This bit indicates a watchdog fault condition has occurred.
0 = 32-kHz oscillation is normal (default).
1 = 32-kHz oscillation stopped or not started, and the watchdog has timed out.
STATUS b4 (ZV): This bit indicates ZVCHG output is clamped.
0 = ZVCHG pin is not clamped (default).
1 = ZVCHG pin is clamped.

LTCLR
The OUTPUT_CONTROL register controls the outputs of the bq29330 and can show the state of the external pin
corresponding to the control.
OUTPUT_ CONTROL b0 (LTCLR): When a fault is latched, this bit releases the fault latch when toggled from 0
to 1 and back to 0 (default =0).
0 = (default)
0->1 ->0 clears the fault latches, allowing STATUS to be cleared on its next read.
