[bit31] TBERR : Tx Block Size Error
When I2Sn_DMAACT:TDMACT is "1" and block transfer through DMA transmission channel is more
than I2Sn_INTCNT:TFTH + 1, this bit is set to 1 and the DMA transmission channel is stopped.
When TBERR is "1" and I2Sn_INTCNT:TBERM is "0", interrupt to CPU occurs.
This bit becomes "0" by software reset.
