Apparatus for controlling the time sequenced energization of a memory unit

DETAILED DESCRIPTION It is, accordingly, an object of the present invention, to provide an improved sequencing control arrangement which obviates the foregoing shortcomings.
It is another object of the present invention to provide an improved sequencing control arrangement which is characterized in requiring fewer individual parts.
It is a further object of the present invention to provide an improved sequencing control arrangement as set forth which is further characterized in exhibiting an improved flexibility relative to the foregoing circuitry.
In accomplishing these and other objects, there has been provided, in accordance with the present invention, a sequencer control arrangement for controlling the sequencing and timing of the energization of controlled elements which arrangement includes a microprocessor unit.
A large number of input lines and output lines are uniquely multiplexed into a relatively small number of I/O port terminals on the microprocessor.
The multiplexing, the sequencing, and all of the delays are effectively controlled by the microprocessor.
