Title "Gigatron Control Unit"
Date "2020-03-20"
Rev "Release"
Comp "Marcel van Kervinck and Walter Belgers"
Comment1 "Bit 5-7 determine the operation performed by the ALU and the type of instruction."
Comment2 "Bit 2-4 select the addressing mode during operations, or the condition during branches."
Comment3 "Bit 0-1 control what is on the data bus: operand (D), RAM, accumulator or input."
Comment4 "The control unit expands 8-bit opcodes (IR) to 19 control lines. The scheme is orthogonal:"
