MPY - 16x16 Signed Multiply

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. Result is also stored as Result variable.

ACLK = 32.768kHz, MCLK = SMCLK = default DCO
