Abstract
In the electronic circuit device with stacked plural components of the same function, this invention enables to select an arbitrary component among plural components by a control element, without setting pre-determined identification information in each component. By installing a sequential logic circuit in each component, and changing a state of the sequential logic circuit by control data transmitted from the component stacked in a preceding stage or the control element, the state of the controlled component is set to a state that accepts a selection made by the control element.
Claims24
An electronic circuit device in which at least one control element and plural components of the same function are stacked, comprising:
- each of said control element and said components includes a means for communication for exchanging data,
- said control element includes a means for transmitting data to direct change of state of said components through said means for communication to one of said components,
- each of said components includes a means for changing an operating state according to said data directing change of state transmitted from said control element or said component of a preceding stage, and
- each of said components includes a means for transmitting said data directing change of state transmitted from said control element or said component of the preceding stage to a component of a latter stage through said means for communication,
- wherein said operating state is at least one of:
- a receiving state to receive said data directing to change state and to change the state of said component to said directed state,
- a transmitting state to transmit said data directing to change state between preceding component and latter component, and
- a selected state to performs directions of said control element.
