  1. firmware: fix illegal IOx manipulation. 

    Something like:

  IOx |= 0x02;
  IOx &= 0x01;

doesn't guaranteed to work unless both of those are already outputs,
since writing an 1 (or 0) to an input doesn't change the value read
back.

In practice this results in weird inconsistent bugs due to board-to-
board variability.

Fixes GlasgowEmbedded#77.
