Method and apparatus for avoiding bi-directional signal fighting of serial interface
A method and apparatus for avoiding bi-directional signal fighting of a serial interface is disclosed. The serial peripheral interface includes a clock signal line and a data line. In this method, during normal operation, a first clock signal is received and transformed to output a second clock signal in the clock signal line, wherein the second clock signal has a first duty period. When the output of the data in the data line switches to input, the second clock signal switches to have the second duty period, wherein the second duty period is larger than the first duty period.
