Notes: (5) This parameter is periodically sampled and not 100%
tested.
(6) t_PUR and t_PUW are the delays required from the time the
third (last) power supply (V_CC, V+ or V-) is stable until
R_W
the specific instruction can be issued. These parameters
are periodically sampled and not 100% tested.
(7) The power-up order of power supplies are V_CC, V+
and V-.
