Concrete signal transmittance process shown in Figure 10 is as follows:
Touch sensor 52 sends to I2C controller 53 ' and touches interrupt signal, and touch interrupt signal, after the process of t1 duration, is transferred to a FIFO buffer 521 by I2C controller 53 ', a length of T1 during transmittance process.
Oneth FIFO buffer 521, after the process of t2 duration, will touch interrupt signal and send to the first codec 522, a length of T2 during transmittance process.
First codec 522, after the coded treatment of t3 duration, will touch interrupt signal and send to the first serializer 523, a length of T3 during transmittance process.
First serializer 523, after the serial process of t4 duration, sends the second codec 8112 to main frame side, a length of T4 during transmittance process by touching interrupt signal.
