Title: Apparatus for indicating clock state using multi LED and method thereof
Inventor: LIM UI SEOK
IPC: G06F11/00
Filed: 2001-12-28
Abstract: PURPOSE: A device and a method for displaying a clock state through multiple LEDs(Light Emitting Diode) are provided to reduce the time and the efforts for debugging to catch a state of a board by diversely displaying the LED state as outputting a high, a low, or a high-Z(Impedance) by comparing an input clock and an output clock with each other. CONSTITUTION: It is checked that a counting clock is inputted(21). If the clock is not inputted, a PLD(Programmable Logic Device) outputs the low output, and the LED maintains the off state regardless of the resistor distributing the applied power. In case that the clock is inputted, if a result comparing a standard clock with the counting clock is smaller than the standard clock, the PLD outputs the high-Z by judging that the inputted clock is an initial clock, and the LED maintains the tail-lights by the resistor distributing the applied power(22,23). In case that the input clock is larger than the standard clock, the PLD outputs the high by judging that the inputted clock is a normal operation clock, and the LED maintains the on state regardless of the resistor(24).
