USBDeferStatusStage Function
Syntax
void USBDeferStatusStage();
Preconditions

None

Remarks

If this function is called, is should get called after the SETUP packet has arrived (the control transfer has started), but before the USBCtrlEPServiceComplete() function has been called by the USB stack. Therefore, the normal place to call USBDeferStatusStage() would be from within the USBCBCheckOtherReq() handler context. For example, in a HID application using control transfers, the USBDeferStatusStage() function would be called from within the USER_GET_REPORT_HANDLER or USER_SET_REPORT_HANDLER functions.
