Abstract: An Integrated Circuit (IC) package is disclosed comprising an IC chip with a microcontroller therein having an n-bit data bus, and up to n pins electrically coupled to the microcontroller. The IC package also includes a control register coupled to the microcontroller for receiving enable and disable signals from the microcontroller. One or more of the pins have one or more functional block associated thereto. Each functional block defines a specified function for its corresponding pin. Thus, each pin having a plurality of corresponding functional blocks has a number of potential functions equal to the number of corresponding functional blocks. The specific function for a given pin is selected by the enable signal from the control register which selects the appropriate functional block upon appropriate command from the microcontroller. By using pins with multiple functions, the instant invention permits an n-bit architecture microcontroller to use less than or equal to n pins.

Abstract: A dual exit tray xerographic machine, having a hot roll fuser, supplies its output copy sheets to a large-capacity exit pocket whereat the sheets are stacked in a vertically extending pile, on a servo-movable elevator platform. The platform height is servo controlled so as to maintain the stack's top sheet at a fixed position relative to a fixed-position, generally horizontally extending, sheet discharge path.Sheet stacking is enhanced by a pair of movable bars. A hold-down bar, in its quiescent position, presses the stack's trailing edge portion down to insure reliable insertion of the next sheet. A pusher bar is maintained in an elevated quiescent position during such insertion.After the sheet has been inserted, the pusher bar lowers onto the stack, at a position between the hold-down bar and the stack's leading edge. The pusher bar thus holds the just-inserted sheet down. The hold-down bar synchronously moves in a generally elliptical path, to first clear the trailing edge of the just-inserted sheet.
