Add customer email
Add a #define to indicate we want to build for the simulator
Skip waiting for clock stable when on simulator
Add set reset latch input to pinout diagram

Change the wait for clock stable to use a single input operation
rather than bit field.  The bitfield is easy in C, but compiler makes
voluminous code.  By using the mask bits, all is better, shorter code, faster
code, uniform execution time.  Only draw back is a little more typing.
Also get rid of one byte of ram, by removing a temp variable.

fill data buffer with test bytes, rather than zeroes.

Now seeing expected results on the "logic analyzer" display.
