Specify USB packet information used by the function ARM_USBH_PipeTransfer.
This section provides the packet information values (parameter packet) for the ARM_USBH_PipeTransfer function.
The following values are defined:
#define ARM_USBH_PACKET_SETUP (0x01UL << ARM_USBH_PACKET_TOKEN_Pos)SETUP Packet.
Generate SETUP transaction.
#define ARM_USBH_PACKET_OUT (0x02UL << ARM_USBH_PACKET_TOKEN_Pos)OUT Packet.
Generate OUT transaction.
#define ARM_USBH_PACKET_IN (0x03UL << ARM_USBH_PACKET_TOKEN_Pos)IN Packet.
Generate IN transaction.
#define ARM_USBH_PACKET_PING (0x04UL << ARM_USBH_PACKET_TOKEN_Pos)PING Packet.
Generate PING transaction (no data packet).
#define ARM_USBH_PACKET_DATA0 (0x01UL << ARM_USBH_PACKET_DATA_Pos)DATA0 PID.
Force DATA0 PID (Packet Identifier) for the initial data packet. When not specified than the driver provides the initial value according to the current state.
#define ARM_USBH_PACKET_DATA1 (0x02UL << ARM_USBH_PACKET_DATA_Pos)DATA1 PID.
Force DATA1 PID (Packet Identifier) for the initial data packet. When not specified than the driver provides the initial value according to the current state.
#define ARM_USBH_PACKET_SSPLIT (0x08UL << ARM_USBH_PACKET_SPLIT_Pos)SSPLIT Packet.
Used when driver does not support automatic handling of SPLIT packets and indicates Start-Split packet. For isochronous OUT it indicates that the High-speed data is in the middle of the Full-speed data payload.
#define ARM_USBH_PACKET_SSPLIT_S (0x09UL << ARM_USBH_PACKET_SPLIT_Pos)SSPLIT Packet: Data Start.
Used when driver does not support automatic handling of SPLIT packets and indicates Start-Split packet. Valid only for isochronous OUT and indicates that the High-speed data is the start of the Full-speed data payload.
#define ARM_USBH_PACKET_SSPLIT_E (0x0AUL << ARM_USBH_PACKET_SPLIT_Pos)SSPLIT Packet: Data End.
Used when driver does not support automatic handling of SPLIT packets and indicates Start-Split packet. Valid only for isochronous OUT and indicates that the High-speed data is the end of the Full-speed data payload.
#define ARM_USBH_PACKET_SSPLIT_S_E (0x0BUL << ARM_USBH_PACKET_SPLIT_Pos)SSPLIT Packet: Data All.
Used when driver does not support automatic handling of SPLIT packets and indicates Start-Split packet. Valid only for isochronous OUT and indicates that the High-speed data is all of the Full-speed data payload.
#define ARM_USBH_PACKET_CSPLIT (0x0CUL << ARM_USBH_PACKET_SPLIT_Pos)CSPLIT Packet.
Used when driver does not support automatic handling of SPLIT packets and indicates Complete-Split packet.
#define ARM_USBH_PACKET_PRE (1UL << 12)PRE Token.
Generate PRE (Preamble) for low-speed devices within a full/low-speed signaling environment.
