Disabling ECT once it's been enabled

I'm working with an MC9S12DP512 and have a couple of questions regarding the enhanced capture timer system.

 

Looking through the datasheet(s) didn't provide an obvious answer but I am wondering if the ECT system can be disabled once it has been enabled.

 

For example, If one of the ECT pins has been enabled for input capture or output compare and I want to change the pin to use it as a general GPIO pin, how do I go about doing that?

 

Also, say one of the ECT pins has been configured as an input capture pin. If that input capture pin is not connected to anything external to the MCU, i.e. the input capture pin is floating, will this create any problems? Will it cause increased power consumption?

 

Thanks
