9.1.3 SPI
Following are the functions related to SPI:
Function Name
Function Prototype
Behaviour Description
Input Parameter 1
SPI_Init
Void SPI_Init ( SPI_Init_Parameter1 Init_Value1,
SPI_Init_Parameter2 Init_Value2)
Initialization of the SPI. By default the SPI is put in slave
mode (hardware selected), baudrate Fcpu/8, the SPI pe-
ripheral is not connected to the external pins (SPE=0), al-
ternate function of SPI output enabled (SOD=0) and
interrupts are disabled. You can change the default config-
uration by selecting input parameters given below.
You can pass one or more parameters by ‘OR’ing them.
SPI_DEFAULT
Reset Value
SPI_ENABLE
Enables the serial peripheral output (SPI alternate func-
tions connected to pins).
SPI_ENABLE_IT
Enables the Interrupt
Selects the clock baudrate by selecting one of the below
parameters.
For SPI_BAUDRATE_4,Clock baudrate is Fcpu/4
For SPI_BAUDRATE_8, Clock baudrate is Fcpu/8, (De-
fault baudrate value)
For SPI_BAUDRATE_16, Clock baudrate is Fcpu/16.
For SPI_BAUDRATE_32, Clock baudrate is Fcpu/32.
For SPI_BAUDRATE_64, Clock baudrate is Fcpu/64.
For SPI_BAUDRATE_128, Clock baudrate is Fcpu/128.
Selects the clock polarity and clock phase by selecting one
of the below parameters.
SPI_CLK_PP_0, For CPOL=0, CPHA =0 (Default clock
polarity and phase)
SPI_CLK_PP_1, For CPOL=0, CPHA =1
SPI_CLK_PP_2, For CPOL=1, CPHA =0
SPI_CLK_PP_3, For CPOL=1, CPHA =1
