How can I change the EMIOSC[n] field in MPC5606B?

[phpark]

Hi. I just started to learn MCU. This question is maybe too simple.

I tried to change the mode of an eMIOS pin.

 

this is a picture of the window in 'CodeWarrior'. And, I'd like to change the Edge Polarity from Set On Match A to Clear On Match A. 

But, I couldn't find the way. 

Please let me know how. Thanks.
