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