Initializes the SPI interface as master.

This function initializes the SPI interface as master and configures the clock based on user input.

Pre-conditions:

• None.

Post condtions:

• Setups the interface for further SPI data transactions.

Parameters:

Parameters:

spi_settings

- see the above bf52x_spi_settings_st structure declaration for.

Returns:

0 if initialization was successful. Else non-zero value.
