Port description

• CLOCK_HZ - Clock signal frequency [Hz].
• CHANGE_COM_US - The time how long each COM is active in [us].
• Clock - Clock signal, active rising edge.
• Reset - Asynchronous reset, active low.
• SegmentsX_i[13:0] - Input segments for each character. High state causes segment visible, bit order is nmlkjihgfedcba.
• DecimalPoints_i[7:0] - Input for decimal points after each character.
• Pin_o[36:1] - Connect to LCD.
