//Select an endpoint ping-pong bufferring mode. Some microcontrollers only | |
//support certain modes. For most applications, it is recommended to use either | |
//the USB_PING_PONG__FULL_PING_PONG or USB_PING_PONG__EP0_OUT_ONLY options. | |
//The other settings are supported on some devices, but they are not | |
//recommended, as they offer inferior control transfer timing performance. | |
//See inline code comments in usb_device.c for additional details. | |
//Enabling ping pong bufferring on an endpoint generally increases firmware | |
//overhead somewhat, but when both buffers are used simultaneously in the | |
//firmware, can offer better sustained bandwidth, especially for OUT endpoints. | |
//------------------------------------------------------ | |
//#define USB_PING_PONG_MODE USB_PING_PONG__NO_PING_PONG //Not recommended | |
#define USB_PING_PONG_MODE USB_PING_PONG__FULL_PING_PONG //A good all around setting | |
//#define USB_PING_PONG_MODE USB_PING_PONG__EP0_OUT_ONLY //Another good setting | |
//#define USB_PING_PONG_MODE USB_PING_PONG__ALL_BUT_EP0 //Not recommended | |

//Select a USB stack operating mode. In the USB_INTERRUPT mode, the USB stack | |
//main task handler gets called only when necessary as an interrupt handler. | |
//This can potentially minimize CPU utilization, but adds context saving | |
//and restoring overhead associated with interrupts, which can potentially | |
//decrease performance. | |
//When the USB_POLLING mode is selected, the USB stack main task handler | |
//(ex: USBDeviceTasks()) must be called periodically by the application firmware | |
//at a minimum rate as described in the inline code comments in usb_device.c. | |

//Option to enable auto-arming of the status stage of control transfers, if no | |
//"progress" has been made for the USB_STATUS_STAGE_TIMEOUT value. | |
//If progress is made (any successful transactions completing on EP0 IN or OUT) | |
//the timeout counter gets reset to the USB_STATUS_STAGE_TIMEOUT value. | |
// | |
//During normal control transfer processing, the USB stack or the application | |
//firmware will call USBCtrlEPAllowStatusStage() as soon as the firmware is finished | |
//processing the control transfer. Therefore, the status stage completes as | |
//quickly as is physically possible. The USB_ENABLE_STATUS_STAGE_TIMEOUTS | |
//feature, and the USB_STATUS_STAGE_TIMEOUT value are only relevant, when: | |
//1. The application uses the USBDeferStatusStage() API function, but never calls | |
// USBCtrlEPAllowStatusStage(). Or: | |
//2. The application uses host to device (OUT) control transfers with data stage, | |
// and some abnormal error occurs, where the host might try to abort the control | |
// transfer, before it has sent all of the data it claimed it was going to send. | |
// | |
//If the application firmware never uses the USBDeferStatusStage() API function, | |
//and it never uses host to device control transfers with data stage, then | |
//it is not required to enable the USB_ENABLE_STATUS_STAGE_TIMEOUTS feature. | |
#define USB_ENABLE_STATUS_STAGE_TIMEOUTS //Comment this out to disable this feature. | |
//Section 9.2.6 of the USB 2.0 specifications indicate that: | |
//1. Control transfers with no data stage: Status stage must complete within | |
// 50ms of the start of the control transfer. | |
//2. Control transfers with (IN) data stage: Status stage must complete within | |
// 50ms of sending the last IN data packet in fullfilment of the data stage. | |
//3. Control transfers with (OUT) data stage: No specific status stage timing | |
// requirement. However, the total time of the entire control transfer (ex: | |
// including the OUT data stage and IN status stage) must not exceed 5 seconds. | |
// | |
//Therefore, if the USB_ENABLE_STATUS_STAGE_TIMEOUTS feature is used, it is suggested | |
//to set the USB_STATUS_STAGE_TIMEOUT value to timeout in less than 50ms. If the | |
//USB_ENABLE_STATUS_STAGE_TIMEOUTS feature is not enabled, then the USB_STATUS_STAGE_TIMEOUT | |
//parameter is not relevant. | |
#define USB_STATUS_STAGE_TIMEOUT (uint8_t)45 //Approximate timeout in milliseconds, except when | |
//USB_POLLING mode is used, and USBDeviceTasks() is called at < 1kHz | |
//In this special case, the timeout becomes approximately: | |
//Timeout(in milliseconds) = ((1000 * (USB_STATUS_STAGE_TIMEOUT - 1)) / (USBDeviceTasks() polling frequency in Hz)) | |
