AD8600
* This program contains subroutines to read and write
* to the AD8600 from the 68HC11.
Additionally, a ramp
* program has been included, to continuously ramp the
* output giving a triangle wave output.
*
* The following connections need to be made:
*
68HC11
AD8600
*
GND
DGND1,2
*
PC0-PC7
DB0–DB7 respectively, data port
*
PB0-PB3

*
ldx
#$00
points to DAC address in 68HC11 mem
ldaa
0,x
puts the address in the accumulator
adda
#$30
set CS, R/W low and LD, EN high
staa
portb
output to portb for control and address
*
inx
