17	help
18	  I2S controller on EP93xx seems to have undocumented HW issue.
19	  Underflow of internal I2S controller FIFO could confuse the
20	  state machine and the whole stream can be shifted by one byte
21	  until I2S is disabled. This option enables IRQ based watchdog
22	  which disables and re-enables I2S in case of underflow and
23	  fills FIFO with zeroes.
24
25	  If you are unsure how to answer this question, answer Y.
