+ * Bit fields for TSSR(Tx Shared Status & Control) error status register:
+ * 31: Indicates an address error when accessed to internal memory
+ * uCode/driver must write "1" in order to clear this flag
+ * 30: Indicates that Host did not send the expected number of dwords to FH
+ * uCode/driver must write "1" in order to clear this flag
+ * 16-9:Each status bit is for one channel. Indicates that an (Error) ActDMA
+ * command was received from the scheduler while the TRB was already full
+ * with previous command
+ * uCode/driver must write "1" in order to clear this flag
+ * 7-0: Each status bit indicates a channel's TxCredit error. When an error
+ * bit is set, it indicates that the FH has received a full indication
+ * from the RTC TxFIFO and the current value of the TxCredit counter was
+ * not equal to zero. This mean that the credit mechanism was not
+ * synchronized to the TxFIFO status
+ * uCode/driver must write "1" in order to clear this flag
