NIOS2 Tristate PIO Direction Whatever...

hi, i wonder if there is someone else who experienced this "PROBLEM":

if i use a 32-bit pio (mapped to some pins on the PROTO2 connector), the PIO-Direction register can be found at "BASE+0x04". fine.

if i use a 12-bit pio it is at "BASE+0x02"!!! http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/mad.gif

the handbook only says:

data = offset 0,

direction = offset 1.

there should be the mark, that the "offset" (which is fix for me if i talk about offset) may VARY depending on the width of the IO...

i remember the old NIOS, the dir-reg was ALWAYS at base+0x04, no matter. i tried to port the old module for the NIOS2, it didnt work.

- so the PIO-Component has changed as well -

thanks altera!

greetings, martin
