Hi Everyone,

I posted this message before but my Email setting was set to NOMAIL for
some unknown reasons.  So I didn't get a reply from any of you.  This
was the message I posted before:

I am stuck and I need your help!  I have 2 PIC16F877 Micros.  They are
communicating with each other through SPI (One master and one slave).
The Master sends 2 bytes of data to the Slave - one is the "command"
byte and one is the "data" byte.  The Master IC always sends out the
"command" byte first follows by a "data" byte. The Slave IC gets
interrupted every time the SPI reception is completed.

Here is my question:  How do I write the code so that the Slave knows
which byte is the "command" byte and which byte is a "data" byte?

Thank you in advance.
Regards,
Thomas
