Enable RX pin pull-ups using AsynchroSerial component

I am working with the HC(S)08 and have integrated the AsynchroSerial component.  I need to enable the pull-up on the RxD pin, so the pin does not float when the component is disabled.


There are no pull-up options for the port pin in the AsynchroSerial properties.


I see some pull-up options for Port E in the CPU component, but this is for unused pins only.


I tried adding a Init_GPIO component and of course this says there is a conflict with the AsynchroSerial component and it won't build.


Without just resorting to writing directly to the port register in the code, what is the correct way to control the pull-up register for the RxD pin?
