bitloop:
out x 1 side 0 [6]; Drive low. Side-set still takes place before instruction stalls.
jmp !x do_zero side 1 [3]; Branch on the bit we shifted out previous delay. Drive high.
do_one:
jmp bitloop side 1 [4]; Continue driving high, for a one (long pulse)
do_zero:
nop side 0 [4]; Or drive low, for a zero (short pulse)
