On page 2-3 of the 68EZ328 user manual it says
"Note: All pins, except EXTAL, support TTL levels. When EXTAL is used as
clock, it needs a CMOS level. To ensure proper low-power operation, all
should be driven to CMOS level. More power is consumed when you use a
level to drive those inputs."
I think this is the info you require. So 5V is OK, but will cause system
to consume more power when going into low power modes.
