NOTE:
For the MC68HC705X4 — as with the MC68HC05X4, this device will
operate down to dc. However, it should be noted that the power
consumption of the EPROM is inversely proportional to frequency. This
means that, at frequencies below f_OP = 100 kHz, the overall power
consumption may exceed the specification limits.
