|
|
This selection enables a simple character driver that supports I2S
|
|
transfers via a read() and write(). The intent of this driver is to
|
|
support I2S testing. It is not an audio driver but does conform to
|
|
some of the buffer management heuristics of an audio driver. It is
|
|
not suitable for use in any real driver application in its current
|
|
form.

---help---
|

This is a fixed timeout value that will be used for all receiver
|
|
transfers. This is in units of system clock ticks (configurable).

The special value of zero disables RX timeouts. Default: 0
