Macro Definition Documentation

◆ ENDPOINT_DIR_MASK

#define ENDPOINT_DIR_MASK 0x80

Endpoint direction mask, for masking against endpoint addresses to retrieve the endpoint's direction for comparing with the ENDPOINT_DIR_* masks.

◆ ENDPOINT_DIR_OUT

#define ENDPOINT_DIR_OUT 0x00

Endpoint address direction mask for an OUT direction (Host to Device) endpoint. This may be ORed with the index of the address within a device to obtain the full endpoint address.

◆ ENDPOINT_DIR_IN

#define ENDPOINT_DIR_IN 0x80

Endpoint address direction mask for an IN direction (Device to Host) endpoint. This may be ORed with the index of the address within a device to obtain the full endpoint address.

◆ EP_TYPE_MASK

#define EP_TYPE_MASK 0x03

Mask for determining the type of an endpoint from an endpoint descriptor. This should then be compared with the EP_TYPE_* masks to determine the exact type of the endpoint.

◆ EP_TYPE_CONTROL

#define EP_TYPE_CONTROL 0x00

Mask for a CONTROL type endpoint or pipe.

Note: See Group_EndpointManagement and Group_PipeManagement for endpoint/pipe functions.

◆ EP_TYPE_ISOCHRONOUS

#define EP_TYPE_ISOCHRONOUS 0x01

Mask for an ISOCHRONOUS type endpoint or pipe.

Note: See Group_EndpointManagement and Group_PipeManagement for endpoint/pipe functions.

◆ EP_TYPE_BULK

#define EP_TYPE_BULK 0x02

Mask for a BULK type endpoint or pipe.

Note: See Group_EndpointManagement and Group_PipeManagement for endpoint/pipe functions.

◆ EP_TYPE_INTERRUPT

#define EP_TYPE_INTERRUPT 0x03

Mask for an INTERRUPT type endpoint or pipe.

Note: See Group_EndpointManagement and Group_PipeManagement for endpoint/pipe functions.

◆ EP_SYNC_TYPE_NO_SYNC

#define EP_SYNC_TYPE_NO_SYNC 0

If Isochronous endpoint, Bits 3..2 = Synchronisation Type (Iso Mode) 00 = No Synchonisation 01 = Asynchronous 10 = Adaptive 11 = Synchronous Bits 5..4 = Usage Type (Iso Mode) 00 = Data Endpoint 01 = Feedback Endpoint 10 = Explicit Feedback Data Endpoint 11 = Reserved

◆ EP_SYNC_TYPE_ASYN

#define EP_SYNC_TYPE_ASYN 1

◆ EP_SYNC_TYPE_ADAPTIVE

#define EP_SYNC_TYPE_ADAPTIVE 2

◆ EP_SYNC_TYPE_SYNC

#define EP_SYNC_TYPE_SYNC 3

◆ EP_USAGE_TYPE_DATA

#define EP_USAGE_TYPE_DATA 0

◆ EP_USAGE_TYPE_FEEDBACK

#define EP_USAGE_TYPE_FEEDBACK 1

◆ EP_USAGE_TYPE_FEEDBACK_DATA

#define EP_USAGE_TYPE_FEEDBACK_DATA 2

◆ EP_USAGE_TYPE_RSV

#define EP_USAGE_TYPE_RSV 3
