Appeal No. 95-3888
Application No. 08/l05,244
The invention pertains to microprocessors configured to
reduce electromagnetic emissions in various applications.
More particularly, this reduction is achieved by causing the
output of the microprocessor driver to be at or near an
optimum voltage level for the particular load being driven.
Independent claim 1 is reproduced as follows:
1. Electronic apparatus comprising mechanical mechanism,
a microprocessor to control said mechanical mechanism, said
microprocessor being on a single substrate and having an
output driver on said substrate to apply control signals
generated by said microprocessor to an electrical line
connected to control said mechanism, said output driver having
at least one circuit which is selectable from an electrical
signal to said one circuit on an enable line to select a first
output voltage level of said output driver when said one
circuit is selected and to select a second output voltage
level lower in voltage level than said first output voltage
level when said one circuit is not selected, said enable line
being connected to a signal originating in said electronic
apparatus to select only one of said first output voltage
level or said second output voltage level during all normal
operations of said apparatus.
