//   MSP430xG46x Demo - 16x16 Unsigned Multiply Accumulate
//
//   Description: Hardware multiplier is used to multiply two numbers.
//   The calculation is automatically initiated after the second operand is
//   loaded. A second multiply accumulate operation is performed after that.
//   Results are stored in RESLO and RESHI. SUMEXT contains the carry of the
//   result.
//
//   ACLK = 32.768kHz, MCLK = SMCLK = default DCO
