Strange 80x86 OPCODE

Doing my thing I hit upon a truly strange op-code:

It's 0F 3D,  i.e. 286+ 2-byte opcode that has 3D as the second
byte.  Problem is,  that I can't find any reference to it anywhere.
It looks like it's either something very new or undocumented.

I considered the possibility of the 0F being a 8088/8086 POP CS,
but the surrounding code excludes this.

Anyone have any idea what that opcode does?

Aki.
