Title: Synchronous data transmitting method
Inventor: ROCHE FRANCK
IPC: G06F13/42
Filed: 2001-11-29
Abstract: PROBLEM TO BE SOLVED: To provide a method for transmitting data between two devices (D1, D2) which can restrain a clock line to an electric potential representing a logic value B opposite to a logic value A respectively using a clock line (CK) maintained at the default value of the logic value A and at least one data line (DT). SOLUTION: By the method of this invention, both devices restrain the clock line to B when the data is transmitted, the device to which the data is transmitted doesn't release the clock line when the device doesn't end reading out the data, and the device which transmits the data maintains the data on the data line at least until when the clock line is released by the device to which the data is transmitted. This method is especially applied to the communication between a microcomputer and a microprocessor.
