Does blank HCS08 micro default to xtal osc?

[Circlotron]

Got an older board that I have to update to HCS08 micros. Several micros on the board. The first has a crystal oscillator and the osc output feeds the next micro osc input and so on. That all works fine because these older micros are programmed externally then plugged into a socket on the board. The newer ones though will be programmed in circuit.

What about the newer HCS08 micros? If any particular micro is blank, will the osc section still feed the clock signal to the next micro? I ask this because these micros have the option of using a given pin as an xtal osc connection or as a GPIO. What is the default for a blank chip?
