All,

 At the risk of sounding snotty, and I don't mean to at all, I did say
 "from my experience", not yours.  And if you say that the /SS pin
 doesn't need to be toggled every time, I believe you.  I don't claim
 to know it all.

 As a matter of fact, I probably should rephrase my response to something
 like this.  From my experience I couldn't really say because I toggled
 the /SS pin after each transaction.  In my applications, the extra time
 to toggle the pin was of no consequence.  As a matter of fact, I just
 wrote a routine that would write one byte at a time to the bus.
 I would load the data to be transmitted into the 'w' register, and call
 the SPIXMT routine.

 Anyway, I believe the mans question was answered.


                                           Regards,

                                             Jim
