|
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. |
