Detailed Description

Serial Peripheral Interface (SPI) Peripheral Driver.

The Serial Peripheral Interface (SPI) is a synchronous serial data communication protocol which operates in full duplex mode. Devices communicate in master/slave mode with 4-wire bi-direction interface.

• Configure the SPI controler as master device or a slave , it should generate clock and chip-select signal if it is set as master .
• Each SPI controller can generates an individual interrupt when data transfer is finished and the respective interrupt event flag IF will be set. The interrupt event flag will generates an interrupt to CPU if the interrupt enable bit IE is set.
• Transfer and receive data which is in your mode

2. SPI Function Description

2.1 SPI device controller configuration

Configure the SPI controller as a master or a slave device. It should generate clock and chip-select signals if it is set as a master device.

2.2 SPI interrupt control

Each SPI controller can generate an individual interrupt when data transfer is finished and the respective interrupt event flag IF will be set. The interrupt event flag will generates an interrupt to CPU if the interrupt enable bit IE is set.

2.3 SPI Transfer and Receive data

Transfer and receive data.

3. SPI Applications

will be added in the future

Note:

Here are descriptions of the common functions of the SPI. The CoX SPI Interface is based on the functions above.
