Abstract
A control method of a control system includes storing output data to a memory according to a buffer pointer when a clock signal converts to a second level from a first level; storing input data to the memory according to the buffer pointer when the clock signal converts to the first level from the second level; and updating the buffer point.
Claims10
A control method of a control system comprising:
- storing output data to a memory of a programmable unit according to a buffer pointer when a clock signal converts to a second level from a first level;
- storing input data to the memory according to the buffer pointer when the clock signal converts to the first level from the second level;
- and
- updating the buffer pointer after the output data and the input data are stored to the memory;
- wherein the output data is transmitted to the programmable unit through a serial general purpose input/output bus, and the input data is transmitted to a host unit through the serial general purpose input/output bus.

A control system comprising:
- a host unit configured to output a clock signal and output data and receive input data;
- a serial general purpose input/output bus coupled to the host unit and configured to transmit the clock signal, the input data and the output data;
- and
- a programmable unit coupled to the serial general purpose input/output bus, configured to receive the clock signal and the output signal and output the input signal, and comprising a memory configured to store the input data and the output data;
- wherein the output data is stored to the memory according to a buffer pointer when the clock signal converts to a second level from a first level;
- the input data is stored to the memory according to the buffer pointer when the clock signal converts to the first level from the second level;
- and the buffer pointer is updated after the output data and the input data are stored to the memory.
