Title:
半導体集積回路
Document Type and Number:
Japanese Patent JP5346259
Kind Code:
B2
Abstract:
A semiconductor integrated circuit is described. A transmitter-receiver transmits and receives data to and from outside by a first external terminal and transmits a first control signal by a second external terminal. When another data is transmitted after the data is transmitted and when a data transmission interval from a time when the data is transmitted to a time when the another data is transmitted is equal to or smaller than a first threshold, the transmitter-receiver continuously outputs, from the first external terminal, a potential level of about ½of a potential level obtained by adding a first potential level and a second potential level, during the data transmission interval, and changes the second potential level of the first control signal to the first potential level when the data transmission interval exceeds the first threshold.
