because only 14 commands are available we can make ( at first sight ) 7 loops like this ( 23 : 55 )
0 >> 9d80
1 >> e104 call & wait second engine
2 >> repeat step 2 for x times ( a081 for 2 cycles)
3 >> 7f02 interdigits pause
4>> e104 call & wait second engine
5>> repeat step 4 for Y times ( a104 for 3 cycles second digit )
6 >> 7f02 interdigit pause
7 >> e104 call & wait second engine
8>> repeat step 7 for x times ( a207 for 5 cycles third digit )
9 >> 7f02 interdigits pause
10 >> e104 call & wait second engine
11 >> repeat step 10 for x times ( a20a for 5 cycles four digit)
12 >> 7f00 last digit pause
13 >> a28c cycle for more pause
14 empty
15 >> 0000 reset

the second engine

9d80
087f pulse up
097f pulse down
e082 trig & wait from engine 1
4000 just in case ....
0000
it is a lot of command available even for black steps

engine 1 jump to second engine steps are the same e104
branch command a000 + 80 * times + start_loop_step_number ( in hexa )

for morse code lovers ... SOS pattern
