Xgate clock source when in stop modes

I'm working on a project using MC9S12XEG128 and I want to take the S12 cpu into full STOP or Pseudo stop mode, but I want the Xgate core to receive data on one of the pins using portH interrupt (Routed to xgate) and a timer.

First of all, I need to know what clock source is available for xgate when the S12 cpu is in full or pseudo stop mode (It seems that xgate uses core clock which seems to be off in stop mode)?

Secondly, what precise timer can I use and how its source clock is provided since the bus clock also seems to be off in stop modes?
