M248 Right Shift Parallel Load Register

Summary The M248 is an 8-bit register module used in the FP15 Floating-Point Processor, constructed by combining two DEC7495 integrated circuits. It functions as a right-shift register when the mode control (MC) input is set to logic 0, allowing data to shift between its two four-bit sections. When the MC input is set to logic 1, the register is decoupled from the right-shift operation and can be configured to perform parallel loading or left-shift operations via the LS input.
