VL53L5CXV0GC - using RSVD6 as GPIO

[Nathan.b]

Hi there,

the VL53L5CX datasheet mentions that RSVD6 is a GPIO and defaults to being an open-drain; 

my question is:

• Can I use RSVD6 programmatically?
• Are there any resources which show it being used?
• Otherwise, how can I use it? 

Many thanks in advance

Hi:

According to the VL53L5CX datasheet and user manual:

Datasheet - VL53L5CX - Time-of-Flight 8x8 multizone ranging sensor with wide field of view

A guide to using the VL53L5CX multizone Time-of-Flight ranging sensor with a wide field of view ultra lite driver (ULD) - User manual

**reserved pins are not supported for customer functional use**.

Although `RSVD6` is described in the datasheet as a GPIO-like open-drain pin by default, it is still explicitly marked as **Reserved** in the pin table.

Also, UM2884 does not provide any API, register description, or usage example for `RSVD6`. The publicly supported pins are `INT`, `LPn`, and `I2C_RST` — **not `RSVD6`**.

Therefore, **`RSVD6` should not be used as a programmable GPIO and should not be relied on in the product design**. From a hardware point of view, it should only be connected as recommended in the datasheet.

Best Regards,
