​Not much point quoting a lot of text when you've just given the link.
Anyway, I digress. The key line in the man page is:​
client-name:client-path/init-string

​so, if you told JACK
-I foo:bar/baz
That means: create a client called "foo", by loading the internal client
from "bar" and give it "baz" as its initialization string.​
​So this:​

internal client, and give it an initialization string of "-dhw:CODEC_1".
The initialization string for internal clients is specific to each client,
but zalsa-in has most of its arguments in common with JACK itself. So
"-dhw:CODEC_1" means "use the device identified as "hw:CODEC_1". ​

​I suggest you remain focused on gettings things working on a command line
before you try to set up a "Pd at boot system". You might prefer that all
these tools just worked without you having to understand too much about
them, but they don't. It will help you in the future to get a more solid
grasp of what is going on and how things work and cooperate.​
