RE: How can I access the TINI IO Ports

 I have a TINIs400 socket, and it doesn't have many
pinouts to access IO ports (except for P5.4-P5.7 and
P1.0, P1.1, which is used for SPI and I2C). So I
intend to interface the LCD directly onto the databus,
but the internal databus don't have any accessible
pins on the socket to play with. That's why I'm asking
how the parallel IO pins are related to the databus.
