PulseBlasterDDS
int status_readback();
Reads the status of the board and returns an integer whose bit representation corresponds to the
status signals described in section IV. Bit zero is stopped; bit one is reset; bit two is running; bit
three is waiting.

// The following program code uses C Functions from 'pbdfuncs' to
// generate and execute a pulse sequence on the PulseBlasterDDS board.
// Be sure to include the DLL (pbd03pc.dll), the library file
// (pbd03pc.lib), the header files (pbd03pc.h and pbdfuncs.h), and source
// file (pbdfuncs.cpp) in the working directory of your C compiler .
