0019 I2S controller on EP93xx seems to have undocumented HW issue.
0020 Underflow of internal I2S controller FIFO could confuse the
0021 state machine and the whole stream can be shifted by one byte
0022 until I2S is disabled. This option enables IRQ based watchdog
0023 which disables and re-enables I2S in case of underflow and
0024 fills FIFO with zeroes.

0026 If you are unsure how to answer this question, answer Y.
