Notes:
If this bit is reset, then the user should consider that a new n-transaction is coming.
This bit is reset by UDPHS_EPTRST register EPT_x (reset endpoint), and by UDPHS_EPTCTLDISx (disable endpoint).
• RX_SETUP/ERR_FL_ISO: Received SETUP/Error Flow
This bit is set by hardware when a valid SETUP packet has been received from the host.
It is cleared by the device firmware after reading the SETUP data from the endpoint FIFO.
This bit is reset by UDPHS_EPTRST register EPT_x (reset endpoint), and by UDPHS_EPTCTLDISx (disable endpoint).
This bit is set by hardware when a transaction error occurs.
This bit is reset by UDPHS_EPTRST register EPT_x (reset endpoint) and by UDPHS_EPTCTLDISx (disable endpoint).
• STALL_SNT/ERR_CRISO/ERR_NBTRA: Stall Sent/CRC ISO Error/Number of Transaction Error
This bit is set by hardware after a STALL handshake has been sent as requested by the UDPHS_EPTSTAx register
FRCESTALL bit.
This bit is reset by UDPHS_EPTRST register EPT_x (reset endpoint) and by UDPHS_EPTCTLDISx (disable endpoint).
This bit is set by hardware if the last received data is corrupted (CRC error on data).
This bit is updated by hardware when new data is received (Received OUT Data bit).
This bit is set at the end of a microframe in which at least one data bank has been transmitted, if less than the number of
transactions per micro-frame banks (UDPHS_EPTCFGx register NB_TRANS) have been validated for transmission inside
this microframe.
This bit is reset by UDPHS_EPTRST register EPT_x (reset endpoint) and by UDPHS_EPTCTLDISx (disable endpoint).
• NAK_IN/ERR_FLUSH: NAK IN/Bank Flush Error
This bit is set by hardware when a NAK handshake has been sent in response to an IN request from the Host.
This bit is cleared by software.
This bit is set when flushing unsent banks at the end of a microframe.
This bit is reset by UDPHS_EPTRST register EPT_x (reset endpoint) and by EPT_CTL_DISx (disable endpoint).

– Received SETUP: (for Control endpoint only)
– Error Flow: (for isochronous endpoint only)
– Isochronous IN transaction is missed, the micro has no time to fill the endpoint (underflow).
– Isochronous OUT data is dropped because the bank is busy (overflow).
– STALL_SNT: (for Control, Bulk and Interrupt endpoints)
– ERR_CRISO: (for Isochronous OUT endpoints) (Read-only)
– ERR_NBTRA: (for High Bandwidth Isochronous IN endpoints)
– NAK_IN:
– ERR_FLUSH: (for High Bandwidth Isochronous IN endpoints)
1. A transaction error occurs when the toggle sequencing does not respect the Universal Serial Bus Specification, Rev 2.0
2. When a transaction error occurs, the user may empty all the “bad” transactions by clearing the Received OUT Data flag
