MEASUREMENT TAKEN WITH ALL INSTRUCTIONS
EXECUTING FROM INTERNAL MEMORY. 50% OF THE
INSTRUCTIONS ARE MULTIFUNCTION (TYPES 1, 4, 5, 12, 13,
14), 30% ARE TYPE 2 AND TYPE 6, AND 20% ARE IDLE
INSTRUCTIONS.
IDLE REFERS TO STATE OF OPERATION DURING EXECUTION
OF IDLE INSTRUCTION. DEASSERTED PINS ARE DRIVEN TO
EITHER V
