rdptr
Character type pointer to PICmicro RAM area for placement of
data read from SPI device.
length
Number of bytes to read from SPI device.
This function reads in a predetermined data string length from
the SPI bus. The length of the data string to read in is passed
as a function parameter. Each byte is retrieved via a call to the
getcSPI function. The actual called function body is termed
ReadSPI. ReadSPI and getcSPI refer to the same function via
a
