Thanks, I found it and I have copied it into the project directory:
From ... C:\Users\"myusername"\mcuxpresso\02\SDKPackages\SDK_2_8_0_MKV46F128xxx16\devices\MKV46F16\drivers
to ...
C:\..\ProjectDirectory\drivers
Thanks a million. I hope there will be a release of possibly new version with Xbara included within the MCUXpresso IDE's SDK management interface.
