The issue where the interrupt of VL53L4CD cannot be used

[Blue666]

I found a problem while using the VL53L4CD. My usual practice is to initialize the VL53L4CD after the terminal is turned on. During subsequent use, I only use Start and Stop to control whether to start ranging.

Now it is found that when I stop, the terminal enters a low-power state. When this state persists for a period of time, when operating VL53L4CD again and sending the start instruction, no interrupt signal can be received. Moreover, after I send VL53L4CD_ClearInterrupt, the interrupt signal remains at a high level all the time.

This is the corresponding register status. Could you help me check what the problem is.

Besides, I noticed that your new driver has fixed a similar problem. Could you help me see how to confirm whether it is the fixed problem.
