Title:
SIGNAL TRANSMISSION METHOD
Document Type and Number:
Japanese Patent JP3282396
Kind Code:
B2
Abstract:
PURPOSE: To avoid collision in a 2-way bus by setting an input state to both of a 1st semiconductor and a 2nd semiconductor so as to switch the mode in the changeover transition of input and output states of the 1st and 2nd semiconductors.
CONSTITUTION: In the case of mode transition, when semiconductor ICs 1, 2 are both set to an input state, collision of outputs is avoided. In order to avoid the collision, a timing signal PBV generated once nearly at one field from a microcomputer is used. In order to set the semiconductor ICs 1, 2 to the input state at the mode transition by using a leading edge of the timing signal PBV and a trailing edge of a succeeding field, the mode from the input state to the output state in the semiconductor IC 1 must be switched just after the mode transition of one field and the mode from the output state to the input state must be transited just before the changeover transition.
