Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
120 words
An integrated circuit configurable as a transmitter and configurable as a receiver, comprising: a configuration pin to which one voltage may be applied to configure the integrated circuit as a transmitter and to which another voltage may be applied to configure the integrated circuit as a receiver; an bidirectional input/output pin for the transmission of data when the integrated circuit may be configured as a transmitter and for the reception of data when the integrated circuit may be configured as a receiver; and circuitry coupled to the configuration pin and the bidirectional input/output pin having a program that allows the integrated circuit to learn an identification code of a transmitter when the integrated circuit may be configured as a receiver.
Claim 2
Dependent Claim
120 words
An integrated circuit configurable as a transmitter and configurable as a receiver, comprising: a configuration pin to which one voltage may be applied to configure the integrated circuit as a transmitter and to which another voltage may be applied to configure the integrated circuit as a receiver; an bidirectional input/output pin for the transmission of data when the integrated circuit may be configured as a transmitter and for the reception of data when the integrated circuit may be configured as a receiver; and circuitry coupled to the configuration pin and the bidirectional input/output pin having a program that allows the integrated circuit to learn an identification code of a transmitter when the integrated circuit may be configured as a receiver.
Claim 3
Dependent Claim
12 words
The integrated circuit of claim 1 wherein the circuitry includes a microcontroller.
Claim 4
Dependent Claim
26 words
The integrated circuit of claim 1 wherein the bidirectional input/output pin is a serial data pin and further including a plurality of bidirectional parallel data pins.
Claim 5
Dependent Claim
51 words
A remote access system, comprising: a transmitter device containing an integrated circuit chip; a receiver device containing the same integrated circuit chip as the transmitter; and wherein the integrated circuit chip may be placed into a learn mode so that it can learn an identification code produced by the transmitter device.
Claim 6
Dependent Claim
51 words
A remote access system, comprising: a transmitter device containing an integrated circuit chip; a receiver device containing the same integrated circuit chip as the transmitter; and wherein the integrated circuit chip may be placed into a learn mode so that it can learn an identification code produced by the transmitter device.
Claim 7
Dependent Claim
26 words
The remote access system of claim 4 wherein the integrated circuit chip is placed into the learn mode by applying a voltage to a programming terminal.
Claim 8
Dependent Claim
51 words
The remote access system of claim 5 wherein the integrated circuit chip contains a configuration terminal to which one voltage is applied to cause the integrated circuit chip to perform as a transmitter and to which another voltage is applied to cause the integrated circuit chip to perform as a receiver.
Claim 9
Dependent Claim
59 words
The remote access system of claim 6 wherein the integrated circuit chip contains pins that are bidirectional so that data may be transmitted therefrom when the one voltage causes the integrated circuit chip to perform as a transmitter and that data may be received thereon when the another voltage causes the integrated circuit chip to perform as a receiver.
