I misinterpreted the data sheet (not hard to do in this particular case) and
thought the mode3 op-codes were mode0 op-codes.  Once I swapped everything
started working.  Having your init code tying 0x57 with mode3 was the clue
that set me on the right path.

Thanks!

| Check the SPI pins, they are used for programming the mega32 too.

| Good luck!
