I'm a new comer of FS's HCS08 seriers MCU and I entercounter a problem of how to use the pin of EXTAL and XTAL.


My questions is:


I want to use an external clock signal as the clock input of HCS08DZ60, the clock signal will be connected to the pin EXTAL, So I want to know how to process the pin XTAL, is it should be connected directely to GND or just floated?


Hope can get help from you.
