Shift Edge
Leading-edge shift is used in transmission. Trailing-edge shift is used in reception.
Data is shifted at the leading edge of the serial clock (or the falling edge of the SCK pin
input/output).
Data is shifted at the trailing edge of the serial clock (or the rising edge of the SCK pin
input/output).
