Access: Read-only
• RSTDT: Reset Data Toggle
This bit is set when UOTGHS_HSTPIPIER.RSTDTS bit is written to one. This will reset the Data Toggle to its initial value

one) or when (INRQ+1) In requests have been processed or when after a Pipe reset (UOTGHS_HSTPIP.PRSTx rising) or
a Pipe Enable (UOTGHS_HSTPIP.PEN rising). This will Freeze the Pipe requests generation.
This bit is cleared when UOTGHS_HSTPIPIDR.PFREEZEC bit is written to one. This will enable the Pipe request
generation.
