MC9S08SH8 ACMP output and BKGD pin

Hello, I am willing to use the MC9S08SH8 in a project. I need to enable the ACMP output (ACMPO pin) so that I can add more hysteresis to the comparator. However, this MCU shares this pin with the BKGD pin. My question is: can I use the BDM pod and the ACMPO functions simultaneously? That is, will the ACMPO interfere with the BDM functions? How should I design my circuit so that I can debug it and retain ACMPO functionality?
 
Any suggestions/help are greatly appreciated. Thanks in advance.
 
Diego.
