MK24FN1M0VDC12: Regarding the 1.5k PU resistor for DP for USB2.0 FS

[huijiejiang]

Hi,

We are using the MK24FN1M0VDC12 USB as the USB2.0 FS device, there is an internal 1.5k PU resistor, is this PU resistor always enabled (connected between DP and USBVDD) or it will be disabled(disconnected from USBVDD) after the host recognizes the device as the FS device? 

Thanks!

Hello,

Actually this had been mentioned in the RM. See below:

So for USB FS device mode, the internal pull-up on D+ are enabled.
