摘要：
An automatic adjustment method for a serial interface circuit and an electronic device having a serial interface circuit perform automatic adjustment to optimum values of the transmitter, under any connection conditions, and without causing rule violations of the serial interface protocol. Various setting values are used in a transmitter and transmission frame retransmit instructions stipulated by the interface protocol are utilized. The frames are transmitted to a connected device using various setting values, and the results from the connected device (5) are used to adjust to the optimum transmitter values, operation specifications (conditions) of the interface protocol can be satisfied, and through retry of frame transfer the optimum values can be calculated.
