This is a pretty tried and true algorithm for sending a block of data 
out a peripheral that interrupts when it is ready for the next bit of 
data, regardless of microprocessor and microcontroller architecture. 
Kick start the first byte and let the ISR go from there.  I have old 
8250 serial port code I wrote in 1989 for an 80286 that works the same way!
