Description

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:

Macro Definition Documentation

#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.
