system.
taken to ensure a low-impedance connection between all MC68030 VCC and
tions of sufficient quality between the MC68030 power supply pins and the
system supplies will result in increased assertion delays for external signals,
a constant supply voltage. It is suggested that a combination of low, middle,
as possible (e.g., a set of 10 FF, 0,1 FF, and 330 pF capacitors in parallel
provides filtering for most frequencies prevalent in a digital system). Similar
In addition to the capacitive decoupling of the power supply, care must be
