This selection enables selection of common SPI options. This option

should be enabled by all platforms that support SPI interfaces.

Set if there is only one active device on the SPI bus. No locking or

SPI configuration will be performed. It is not necessary for clients to

lock, re-configure, etc..

Devices on the SPI bus require out-of-band support to distinguish
|
||
|
|
command transfers from data transfers. Such devices will often support
|
||
|
|
either 9-bit SPI (yech) or 8-bit SPI and a GPIO output that selects
|
||
|
|
between command and data.
