Hidden TPM channel in 32-pin GT16A

32-pin MC9S08GT16A has no IO pin for TPM2CH1. But I think I can still use TPM2CH1 in the capture mode to generate interrupts. Both the gates and the pad for TMP2CH1 are on the silicon, just there is no pin that connects to that pad. Right?

My question is, can I use TPM2CH2, -3, -4 this way? Is it possible that the gates are all there, but no pads or pins to bring them out?
Any insiders' hint?
