 Read-only 

0 = no effect.

1= If set a STALL answer will be done to the host for the next handshake.

This bit is reset by hardware upon received SETUP.

Toggle Sequencing:

–

 it indicates the PID Data Toggle that will be used for the next packet sent. This is not relative to 

the current bank.

– CONTROL and OUT endpoint:

These bits are set by hardware to indicate the PID data of the current bank:

 In OUT transfer, the Toggle information is meaningful only when the current bank is busy (Received OUT

Data = 1).

These bits are updated for OUT transfer: 

– a new data has been written into the current bank.

– the user has just cleared the Received OUT Data bit to switch to the next bank.

 For High Bandwidth Isochronous Out endpoint, it is recommended to check the UDPHS_EPTSTAx/ERR_TRANS

bit to know if the toggle sequencing is correct or not.
