Well, for what it's worth, I was able to speed it up slightly by doing
the following:

PA_DR |= (byte)0x80;

Weird how you have to prod the compiler to generate something it should
have inferred fro the PA_DR register which is only 8 bits.

Still, even with that, I only get a speed of 250kHz, still WELL below
what I'd expect of a processor running at 50MHz, that's still 200 cycles
just to flip a bit back and forth. TTYL
