//   MSP430F54x Demo - 8x8 Signed Multiply
//
//   Description: Hardware multiplier is used to multiply two numbers.
//   The calculation is automatically initiated after the second operand is
//   loaded. Results are stored in RESLO, RESHI and SUMEXT = FFFF if result is
//   negative, SUMEXT = 0 otherwise.
//
//   ACLK = 32.768kHz, MCLK = SMCLK = default DCO
