Link balance adjustment system and link balance adjustment method

A link balance adjustment system, comprising:

• a connection port, configured to initiate a balance adjustment process through an interrupt signal;
• and
• a microprocessor, configured to transmit the adjustment parameter to the connection port according to an adjustment parameter of an external device provide by a register and;
• wherein the microprocessor initiates a measurement signal, and the measurement signal is used to enable the connection port to measure signal quality after the adjustment parameter is applied by the external device;
• wherein the microprocessor determines whether the connection port performs a preprocessing;
• when the microprocessor determines that the connection port performs the preprocessing, the connection port performs the preprocessing and generates preprocessing data;
• the connection port transmits the preprocessing data to the register;
• the microprocessor reads the preprocessing data in the register or the signal quality, and the microprocessor determines whether a signal measurement result meets a standard according to the preprocessed data or the signal quality, when the microprocessor determines that the signal measurement result meets the standard, the microprocessor clears the interrupt signal, and marks in the register that the balance adjustment process is complete.
