Welcome in the forum, Charlie.
Look in Component catalog -> Digital -> Logic. There you'll find the SmartIO component.
The OP means that the SmartIO have a DU inside, but the configuration of the DU is not available on the SmartIO configuration window.
Maybe it's available only writing to specific registers directly but i haven't read the 4S Register TRM.
This http://iotexpert.com is the blog of Alan Hawse, Cypress Engineer, all i know about SmartIO i learned reading his tutorials, maybe you can drop him a question, hope he can help you.
May be my word was not clear.
I got the SmartIO component, but this component do not have DU(data unit) configure.
My question is: how to use DU in the Smart I/O?
Thanks your reply, i am looking Alan's blog and learning.
No problem :D, please let us know if you get the DU working.
Data unit is not supported for PSoC4000S in the current version(4.0) of creator. It may get support in future versions.
Thanks, hope get it ASAP. :)
The SmartIO Data Unit is supported in PSoC Creator 4.1. This is scheduled for release approximately March 10, 2017, our work-week 10. I have two project using the Data Unit in an early version of 4.1. One is a divide by 4 using the DU for a low-phase error FSK modulator. The other is a 15 bit shift register for a correlator in an FSK demodulator. If you are willing to sign sufficient releases to work with a beta version, I can then get approval from software management and ship you a link to download same. I can also send copies of my working projects. Know that these are development projects and are not claimed to be production worthy, but they do work. I'm doing these in CY8C4A45, the analog coprocessor, but the digital stuff is applicable to any PSoC4 with Smart IO. Contact me by direct email at email@example.com; I can call you on the phone if you prefer. You can also check out my FSK app notes to get a feel for how these things work.

Thanks your kindly reply.
Now i am busy on other development, i prefer to wait official 4.1 release at March and will have a try.
The AppNotes will available until the release of Creator 4.1? (i guess the answer is yes)
There are no app notes on SmartIO. There will be no app notes on SmartIO before Creator 4.1 comes out. There are three code examples available, CE209974, 75, and 76, but these do not address the Data Unit. You'll have to wait. Sorry.
Any news on the App Notes on SmartIO?
