unsigned char WriteSPI(unsigned char ByteToSend)

If the application firmware is expecting to receive
valid data – in either SPI Slave or Master mode –
the firmware must read from the SSPBUF register
before writing the next byte to transmit to SSPBUF.
If the firmware does not read from SSPBUF, the
BF bit (SSPSTAT<0>) can still be set from the pre-
vious transaction. If the BF bit is set, the incoming
data byte is blocked from transferring from the
SSPSR Shift register to the SSPBUF register. If
the firmware then reads from SSPBUF, the data
read will not match the data most recently received
on the SDI pin.
In the earlier silicon revision (B5), incoming data
bytes received on the SDI pin are always trans-
ferred from SSPSR to SSPBUF, regardless of the
state of the BF bit.

SAMPLE C CODE FOR TRANSFERRING SPI DATA
;Perform read, even if the data in SSPBUF is not important
;In this example, let’s send “0xA5” to the other SPI device.
;The data received should be valid.
// Reads from SSPBUF, ensures BF bit is clear before
// sending the next byte.
// Wait until the transmission is complete.
// The data received should be valid.
PIC18F2458/2553/4458/4553
Work around
If the firmware expects to receive valid data,
always clear the BF bit by reading from SSPBUF
prior to writing to SSPBUF, even when the current
data in SSPBUF is not important. Sample work
around code, suitable for all silicon revisions, is
given in Example 1 (Assembly language) and
Example 2 (C language).
