MAX 7000 unused dedicated inputs

Hello all, I am using a MAX 7000AE CPLD. I don't plan on using the GCLK, GCLRn, OE1, or OE2. What should be done with these unused pins? Left floating or driven to GND? Pull GCLRn up to VCC? ...

It never a good practise to leave input pins floating. I dont see a Pin connection guideline (pcg) for Max7000, but there is one for MAXV. Perhaps you can check the PCG if it should be pull up to whatever supply or pull down or direct GND as reference.
