STALL_SNT
STALL is returned by a function in response to an IN token or after the data phase of an OUT or
in response to a PING transaction. STALL indicates that a function is unable to transmit or
receive data, or that a control pipe request is not supported.
To stall an endpoint, set the FRCESTALL bit in UDPHS_EPTSETSTAx register and after the
STALL_SNT flag has been set, set the TOGGLE_SEG bit in the UDPHS_EPTCLRSTAx
register.
Set the FRCESTALL bit in UDPHS_EPTSETSTAx register.
