CCS C Compiler Manual PCB / PCM / PCH

Examples:
while #use spi(MATER, SPI1, baud=1000000, mode=0, stream=SPI1_MODE0)
spi_inspi_init(SPI1_MODE0, TRUE); //initialize and enable SPI1 to setting in #USE
SPI
spi_inspi_init(FALSE); //disable SPI1
spi_inspi_init(250000);//initialize and enable SPI1 to a baud rate of 250K

stream – is the SPI stream to use as defined in the STREAM=name
option in #USE SPI.
data- the variable or constant to transfer via SPI
Nothing.
Writes data into the SPI buffer without waiting for transfer to be
completed. Can be used in conjunction with spi_xfer() with no
parameters to transfer more then 8 bits for PCM and PCH device, or
more then 8 bits or 16 bits (XFER16 option) for PCD. Function is useful
when using the SSP or SSP2 interrupt service routines for PCM and PCH
device, or the SPIx interrupt service routines for PCD device.
This function is only available on devices with SPI hardware.
#USE SPI, and the option SLAVE is used in #USE SPI to setup PIC as a
SPI slave device

Returns:
Function:
value = spi_read ([data])
value = spi_read2 ([data])
data – optional parameter and if included is an 8 bit int.
An 8 bit int
Return a value read by the SPI. If a value is passed to the spi_read() the data
