NOTE:
These MC68HC705JJ7/MC68HC705JP7 device options are available:
A line over a signal name indicates an active low signal. For example,
RESET is active high and RESET is active low.
Any reference to voltage, current, or frequency specified in the following
sections will refer to the nominal values. The exact values and their
tolerance or limits are specified in
Specifications.
