Each wave is transmitted in the order specified. A wave may
only occur once per chain. Waves may be transmitted multiple
times by using the repeat command. The repeat command
specifies a wave id and a count. The wave id must occur
earlier in the chain. All the waves between wave id and the
repeat command are transmitted count times.
A blocks of waves may be transmitted multiple times by
using the loop commands. The block is bracketed by loop
start and end commands. Loops may be nested.
Repeat commands may not be nested. The minimum repeat
count is 2. A maximum of 5 repeat commands is supported
per chain.
Delays between waves may be added with the delay command.
The following command codes are supported:

Repeat @ 255 wid C0 C1 C2 @ Repeat from wid count times
count = C0 + C1*256 + C2*65536
Loop Start @ 255 0 @ Identify start of a wave block
Loop Repeat @ 255 1 x y @ loop x + y*256 times
Delay @ 255 2 x y @ delay x + y*256 microseconds

Each wave is transmitted in the order specified. A wave may only
occur once per chain. Waves may be transmitted multiple times by
using the repeat command. The repeat command specifies a wave id
and a count. The wave id must occur earlier in the chain. All the
waves between wave id and the repeat command are transmitted count
times.
Each wave is transmitted in the order specified. A wave may
occur multiple times per chain.
Repeat commands may not be nested. The minimum repeat count is 2.
A maximum of 5 repeat commands is supported per chain.
A blocks of waves may be transmitted multiple times by using
the loop commands. The block is bracketed by loop start and
end commands. Loops may be nested.
Delays between waves may be added with the delay command.
The following command codes are supported:
Name @ Cmd & Data @ Meaning
Repeat @ 255 wid C0 C1 C2 @ Repeat from wid count times
count = C0 + C1*256 + C2*65536
Loop Start @ 255 0 @ Identify start of a wave block
Loop Repeat @ 255 1 x y @ loop x + y*256 times
Delay @ 255 2 x y @ delay x + y*256 microseconds
The code is currently dimensioned to support a chain with roughly
600 entries and 20 loop counters.
