Transaction Error Type constants
Transaction Error Type constants represent various transaction errors specified by a numerical value.
/* USB Host Transaction Error Type */
enum {
USBH_TR_NO_ERROR = 0, /* No error */
USBH_TR_ERROR_BSTUFF = 1, /* Bit stuff error */
USBH_TR_ERROR_PID = 2, /* PID check error */
USBH_TR_ERROR_CRC = 3, /* CRC error */
USBH_TR_ERROR_BUSTT = 4, /* Bus Turn-around Time error */
USBH_TR_ERROR_FEOP = 4, /* False EOP error */
USBH_TR_ERROR_BABBLE = 4, /* Babble or Loss of Activity error */
USBH_TR_ERROR_EOF = 5, /* Transaction during EOF error */
USBH_TR_ERROR_DOVER = 6, /* Data Overrun error */
USBH_TR_ERROR_DUNDER = 7, /* Data Underrun error */
USBH_TR_ERROR_OTHER = 8, /* Other errors */
};
