SDI1
Hi-byte data loaded from memory
SDI1 = data in location 0000H
$0001
SDI2
Low-byte data loaded from memory
SDI2 = Data in location 0001H
#SDI1
#$1000
Stack pointer at 1st byte to send via SDI
Stack pointer at on-chip registers
Assert /RS
De-assert /RS
Assert /CS
Get a byte to transfer via SPI
Write SDI data reg to start xfer
Loop to wait for SPIF
SPIF is the MSB of SPSR
(when SPIF is set, SPSR is negated)
Increment counter to next byte for xfer
Are we done yet
If not, xfer the second byte
Latch register & update AD8801
When done, restore registers X , Y & A
** Return to Main Program **
