Can I ground the VG2 pin on the QPL7442?

Can I ground the VG2 pin on the QPL7442? Trying to drop this onto an existing board. Also, if pin 6 is not grounded (again, dropped onto existing board) will it still function correctly?

Hi,

Pin 6 has no internal connection, so it does not need to be grounded. It can be left not connected.

However, VG2 (pin 5) has an internal connection and cannot be grounded; it should be left as not connected as per the datasheet.
