RE: How can I access the TINI IO Ports

The pins on the TINIs400b's j28, labeled parallel I/O are intended to be
connected to the CPLD, U12.  Refer to the TINIs400b schematic:

ftp://ftp.dalsemi.com/pub/tini/reference_designs/TINIm400/TINIs400b.PDF

This CPLD is not normally populated.

Refer to ftp://ftp.dalsemi.com/pub/tini/ds80c400/cpld/ for the example CPLD
code that provides the user IO.
