In the 2nd version, I kept using HW names, for example:

1. "urt0" as the function name,

2. "SM_URT0_TXD" as the pin name (group name)

to keep sync with HW, especially the pin names are the same as HW's, because
that's what HW doc, sch, etc. call them. IMHO, using a different name with HW
is not a good idea, what do you think?

Thanks,
Jisheng
