[Tinyos-devel] problem with msp430 spi unconfigure.

[Vlado Handziski]

I think that we should return the normal power manager to the USARTs (that
was removed in some of the refactoring) and deal with this there. When there
is no PM, the unconfigure should indeed leave the module in reset to
minimize the consumption, however, I vaguely remember that we checked with a
scope that the difference was almost undetectable.
