Notes 1. If the wLength value is lower than the prepared value, the wLength value is returned; if the wLength value is
the prepared value or higher, the prepared value is returned.
2. The CLEAR_FEATURE request clears UF0 device status register L (UF0DSTL) and UF0 EPn status register
L (UF0EnSL) (n = 0 to 4, 7) when ACK is received in the status stage.
