/**
* cvmx_stx#_int_reg
*
* Notes:
* * CALPAR0
* This bit indicates that the Spi4 calendar table encountered a parity
* error on bank0 of the calendar table memory. This error bit is
* associated with the calendar table on the TX interface - the interface
* that drives the Spi databus. The calendar table is used in Spi4 mode
* when using the status channel. Parity errors can occur during normal
* operation when the calendar table is constantly being read for the port
* information, or during initialization time, when the user has access.
* This errors will force the the status channel to the reset state and
* begin driving training sequences. The status channel will also reset.
* Software must follow the init sequence to resynch the interface. This
* includes toggling INF_EN which will cancel all outstanding accumulated
* credits.
*
* * CALPAR1
* Identical to CALPAR0 except that it indicates that the error occured
* on bank1 (instead of bank0).
*
* * OVRBST
* STX can track upto a 512KB data burst. Any packet larger than that is
* illegal and will cause confusion in the STX state machine. BMI is
* responsible for throwing away these out of control packets from the
* input and the Execs should never generate them on the output. This is
* a fatal error and should have STX_INT_SYNC[OVRBST] set.
*
* * DATOVR
* FIFO where the Spi4 data ramps upto its transmit frequency has
* overflowed. This is a fatal error and should have
* STX_INT_SYNC[DATOVR] set.
*
* * DIPERR
* This bit will fire if any DIP2 error is caught by the Spi4 status
* channel.
*
* * NOSYNC
* This bit indicates that the number of consecutive DIP2 errors exceeds
* STX_DIP_CNT[MAXDIP] and that the interface should be taken down. The
* datapath will be notified and send continuous training sequences until
* software resynchronizes the interface. This error condition should
* have STX_INT_SYNC[NOSYNC] set.
*
* * UNXFRM
* Unexpected framing data was seen on the status channel.
*
* * FRMERR
* This bit indicates that the number of consecutive unexpected framing
* sequences STX_DIP_CNT[MAXFRM] and that the interface should be taken
* down. The datapath will be notified and send continuous training
* sequences until software resynchronizes the interface. This error
* condition should have STX_INT_SYNC[FRMERR] set.
*
* * SYNCERR
* Indicates that an exception marked in STX_INT_SYNC has occured and the
* TX datapath is disabled. It is recommended that the OVRBST, DATOVR,
* NOSYNC, and FRMERR error conditions all have their bits set in the
* STX_INT_SYNC register.
