Patent ID: 8086901

Claim:
A timer circuit electronically connecting with a debug card to measure a running time of a procedure of a basic input/output system of an electronic device, comprising: a processing module comprising a microprocessor unit (MCU); a setting module operable to set a first debug code and a second debug code corresponding to an initial stage and a final stage of the procedure respectively; a display module; wherein the MCU is operable to read a debug code of the debug card continuously and determine whether the debug code is the same as the first debug code; wherein the MCU is operable to start timing and determine whether the debug code is the same as the second debug code; wherein the MCU is operable to finish timing and display a timing result on the display module; and wherein the MCU comprising a first input unit operable to read the debug code, and a second input unit operable to read a signal sent from the setting module.
