• NAK_OUT: NAK OUT
This bit is set by hardware when a NAK handshake has been sent in response to an OUT or PING request from the Host.
This bit is reset by UDPHS_EPTRST register EPT_x (reset endpoint) and by EPT_CTL_DISx (disable endpoint).
• CURRENT_BANK/CONTROL_DIR: Current Bank/Control Direction
These bits are set by hardware to indicate the number of the current bank.
Note:
This bit is reset by UDPHS_EPTRST register EPT_x (reset endpoint) and by UDPHS_EPTCTLDISx (disable endpoint).
0 = a Control Write is requested by the Host.
1 = a Control Read is requested by the Host.
Notes:
• BUSY_BANK_STA: Busy Bank Number
These bits are set by hardware to indicate the number of busy banks.
• BYTE_COUNT: UDPHS Byte Count
Byte count of a received data packet.
This field is incremented after each write into the endpoint (to prepare an IN transfer).
This field is decremented after each reading into the endpoint (OUT transfer).
This field is also updated at RX_BK_RDY flag clear with the next bank.
This field is also updated at TX_PK_RDY flag set with the next bank.
This field is reset by EPT_x of UDPHS_EPTRST register.

Value
IN endpoint: it indicates the number of busy banks filled by the user, ready for IN transfer.
OUT endpoint: it indicates the number of busy banks filled by OUT transaction from the Host.
– Current Bank: (all endpoints except Control endpoint)
– Control Direction: (for Control endpoint only)

The current bank is updated each time the user:
- Sets the TX Packet Ready bit to prepare the next IN transfer and to switch to the next bank.
- Clears the received OUT data bit to access the next bank.
1. This bit corresponds with the 7th bit of the bmRequestType (Byte 0 of the Setup Data).
2. This bit is updated after receiving new setup data.
