;   MSP430x24x 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. (In this eg: 0x04*0x84 = FFFFFE10)
;
;   ACLK = 32.768kHz, MCLK = SMCLK = default DCO
