Notes: (4) This parameter is periodically sampled and not 100%
tested
(5) t_PUR and t_PUW are the delays required from the time
the (last) power supply (V_CC-) is stable until the specific
instruction can be issued. These parameters are period-
ically sampled and not 100% tested.
(6) This is not a tested or guaranteed parameter and should
be used only as a guideline.
