Note :
These bits clear the sequence bit (the bit controlled by H/W) and turns the data PID into DATA 0 PID.
This bit immediately returns to “0” after writing “1”.
In the transfers after the sequence bit is cleared, the sequence bit is toggled through H/W control.
At S/W reset (USBE bit = “1”) and USB bus reset, the sequence bit of each endpoint is not cleared.

Be sure to set the response PID of the endpoint whose sequence bit is desired to be cleared to NAK (EP0_PID
bits = “00”/EPi_PID bits = “00”) before writing “1” to this bit.
