void USBEnableEndpoint(
    BYTE ep, 
    BYTE options
);

Description

This function will enable the specified endpoint with the specified options.

Typical Usage:

Copy Code

void USBCBInitEP(void)
{
    USBEnableEndpoint(MSD_DATA_IN_EP,USB_IN_ENABLED|USB_OUT_ENABLED|USB_HANDSHAKE_ENABLED|USB_DISALLOW_SETUP);
    USBMSDInit();
}

In the above example endpoint number MSD_DATA_IN_EP is being configured for both IN and OUT traffic with handshaking enabled. Also since MSD_DATA_IN_EP is not endpoint 0 (MSD does not allow this), then we can explicitly disable SETUP packets on this endpoint.

Preconditions

None
