Abstract
A serial transmission control system accesses data based on status signal, includes a timing register for storing a predetermined times of a basic period width and a predetermined number of trigger times, a data buffer for storing data, a timing control state machine for outputting the status signal until receiving a terminal signal. The status signals have a period width complying with the predetermined time of the basic period width. While the terminal signal is received and a number of outputting the status signals does not comply with the predetermined number of trigger times, the status signal will keep outputting until complying with the predetermined number of trigger times. A transforming circuit is for accessing the data stored in the data buffer.
Claims7
A serial transmission control system capable of accessing data according to a status signal, the serial transmission control system comprising:
- a timing register for storing a predetermined time of a basic period width and a predetermined number of trigger times;
- a data buffer for storing data;
- a timing state machine for repeatedly outputting the predetermined number of triggering times of the status signals when receiving a starting signal and until receiving a terminal signal, and for stopping outputting the state signal when completely outputting the predetermined number of triggering times of the state signals;
- wherein the period width of the status signals complies with the predetermined time of the basic period width;
- and
- a transformer for accessing the data stored in the data buffer in response to the state signal generated by the timing state machine.
