1. In OUT transfer, the Toggle information is meaningful only when the current bank is busy (Received OUT Data = 1).
2. These bits are updated for OUT transfer:
3. For High Bandwidth Isochronous Out endpoint, it is recommended to check the UDPHS_EPTSTAx/ERR_TRANS bit to know
4. This field is reset to DATA1 by the UDPHS_EPTCLRSTAx register TOGGLESQ bit, and by UDPHS_EPTCTLDISx (disable
