The SPI Master Synchronous Driver
=================================
The serial peripheral interface (SPI) is a synchronous serial communication
interface.
SPI devices communicate in full duplex mode using a master-slave
architecture with a single master. The master device originates the frame for
reading and writing. Multiple slave devices are supported through selection
with individual slave select (SS) lines.
Features
--------
* Initialization/de-initialization
* Enabling/disabling
* Control of the following settings:
* Baudrate
* SPI mode
* Character size
* Data order
* Data transfer: transmission, reception and full-duplex
Applications
------------
Send/receive/exchange data with a SPI slave device. E.g., serial flash, SD card,
LCD controller, etc.
Dependencies
------------
SPI master capable hardware
Concurrency
-----------
N/A
Limitations
-----------
The slave select (SS) is not automatically inserted during read/write/transfer,
user must use I/O to control the devices' SS.
Known issues and workarounds
----------------------------
N/A
