USB controller on MCF5474

i have some questions about the MCF5474 USB controller:

1. Why is possible in the USBAISR register, that IN as well as OUT Tocken are seted in a definitely OUT Endpoint Interrupt, although the ACK Bit for In-transaction is not seted???

2.Why are core-interrupt as well as endpoint(0-7)-interrupt at the same time there, if the host controller send a In-Tocken to the MCF5474 ???

Thanks in advance for the help.
