Abstract:
1. A method for programming a multi-bit digital address into a device by using a single external multifunction connection and a serial data bus, said method comprising the steps of: providing an external serial data bus connection; providing serial interface and control logic, the serial interface and control logic having an input coupled to the external serial data bus connection; providing a switch having a control input coupled to the serial interface and control logic; providing a single external connection coupled to the switch; providing an analog-to-digital converter (ADC) coupled to the switch; providing an address register coupled to the ADC and the serial interface and control logic; providing a primary function coupled to the switch; providing first and second resistors coupled to the single external connection; coupling together the single external connection and the ADC with the switch during an address definition operation; creating a certain analog value with the first and second resistors; converting the certain analog value to a multi-bit digital address with the ADC; storing the multi-bit digital address in the address register during an address detection operation; and coupling the single external connection to the primary function during a normal operation.
