Smartpin variable pulse stream

Another useful smartpin mode is outputing a number of pulses with controlled high and low duration.
In this example we output 16 pulses with a high/low duration of 40us and 20us calculated from a 300MHz clock.
Then we wait for the smartpin to acknowledge and output 3 pulses. P50 is used as a reference.

This is it in one line of code (50 HIGH first for scope. The ,,, are just for reability )
48 PIN ... 12000 6000 HILO ... 50 LOW ... 16 PULSES ... WAITPIN ... 3 PULSES ... 50 HIGH

Let's break that one-liner down
First off, my clock is 300MHz so 40us= 12000 and I specify P48 as the target smartpin.
HILO takes high and low count and sets up the Smartpin, so I expect 40us high, 20us low
LOW drives P50 low.
PULSES writes wypin with that value (just an alias) to generate 16 pulses of set timing
WAITPIN waits for smartpin ack
3 more PULSES without any other changes
HIGH drives P50 high to indicate that the code has completed (although the smartpin is still busy)
