Generating Square wave based external low power crystal?

Hi,
 
I have a 32.768kHz external xtal. I want to generate square wave based this crystal to measure its frequency. I can't measure it directly from EXAL pin due to probe capacitance. I have a high precision frequency counter. Do you know a way to generate a signal based directly this crystal without using internal DCO? I don't want jitter at output.
 
MCU is MC9S08LC60
CW v5.1 C Compiler
 
I tried common outputs of LCD module of the MCU. but no change. I didn't understand why it is not :smileysad:
 
Thank you.
