6.2 STATUS Register (Address = 2h) [reset = 0h]
Table 6 shows the STATUS register.
Return to Summary Table .
This register contains the device status. A read operation to this register clears the status bits. This
register is volatile, so it loses its contents if the voltage on the VIN pin becomes less than the UVLO
threshold or a low logic level is applied to the EN pin.
