result = spi_data_is_in()

None
0 (FALSE) or 1 (TRUE)
Returns TRUE if data has been received over the SPI.
This function is only available on devices with SPI hardware.

value = spi_read (data)
value = spi_read2 (data)
data is optional 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 spi_read() the data will be
clocked out and the data received will be returned. If no data is ready, spi_read()
will wait for the data if A SLAVE or return the last DATA clocked in from spi_write.
If this device is the master then either do a spi_write (data) followed by a spi_read()
or do a spi_read (data). These both do the same thing and will generate a clock. If
there is no data to send just do a SPI_READ(0) to get the clock.
If this device is a slave then either call spi_read() to wait for the clock and data or
use spi_data_is_in() to determine if data is ready.
This function is only available on devices with SPI hardware.
