Can such interface be handled with SHIFTOUT? (Macroblock MBI5026 LED driver)

[CuriousOne]

yes, checked all that
tried to pull CLK, SDI, LE pins high/low - all work fine. Checked all wirings and contacts - everything is fine.
A little note - voltage on all output pins is about +3V regarding to GND, and does not change whatever command I send.

Tried to play with OE pin - no change, it does not care whenever pull it high or low...
