FRDM-K64F USB host driver

Hi,

I am learning the code of the KHCI USB host driver in recent days. I found that the status register named USBx_STAT (0x40072090) has never been used in the USB host driver but used in the USB device driver. Does this mean that this register only involves the USB device mode?

Thanks.
