As pointed out by Sean, on mx23 reference manual we have the following text describing HOSTDISCONDETECT: "Due to a on chip issue (Errata #2791), software must pay attention to when to assert the HOSTDISCONDETECT bit description has the following: ENHOSTDISCONDETECT bit in HW_USBPHY_CTRL register: 1. Only set HW_USBPHY_CTRL.ENHOSTDISCONDETECT during high speed host mode. 2. Do not set HW_USBPHY_CTRL.ENHOSTDISCONDETECT during the reset and speed negotiation period. 3. Do not set HW_USBPHY_CTRL.ENHOSTDISCONDETECT during host suspend/resume sequence." and the same is not present on mx28 reference manual. How can we make sure we are not violating the point 2 above?
