I
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.
12
Applies to PBGA package type.
13
Output pin capacitance is the capacitive load for any three-stated output pin.
