ooops! Probably a bit too much having about 230 signals with only 24 UDBs. This is a PSoC and not an FPGA.

   

An additional error you made is to connect one pin to an 8-bit bus which will not work.

   

So independent of what the meaning of the error 702 is, your design will not fit.

Can you show us the offending line or even post your complete project so that we all can have a look at? To do so, use

   

Creator -> File -> Create Workspace Bundle (minimal) and then attach the resulting archive. (do NOT use chrome, will not attach a file)

You will have to use DataPath (much new to learn).

   

In the "Component Author Guide" are shown the register naming patterns of DataPath registers which you should re#define in your component's .h template file. There are videos concerning DataPath. I can see, that English is not your native language, but there is much material to read when you want to use DataPath objects.

Datasheet and TRM of PSoC 3 state: there are 24 UDBs within the chip, each containing 1 DataPath (and some more stuff).
