In an implementation, a selectable integrated circuit interface includes selectable integrated circuit interface configurations that can each interface an integrated circuit. A selection circuit generates a selection signal to select an individual selectable integrated circuit interface configuration, and logic couples a clock signal and data to a selected integrated circuit interface configuration.

In an implementation of multiple integrated circuit control, a multiple integrated circuit controller initiates and controls data transactions between the multiple integrated circuit controller and integrated circuits. A data link communicates the data transactions between the multiple integrated circuit controller and the integrated circuits, and a clock signal link communicates a clock signal generated by the multiple integrated circuit controller to the integrated circuits. The multiple integrated circuit controller includes a first push-pull driver to drive the data transactions on the data link and includes a second push-pull driver to drive the clock signal on the clock signal link.

A resonant mode energy recovery circuit is disclosed for supplying drive pulses to an electroluminescent (EL) display arranged as a matrix of pixels addressed by a plurality of column and row electrodes. An external inductor is used to alternately store and supply energy from the column electrodes of the EL display which has an impedance equivalent to an array of capacitors and resistors. Switching transistors and diodes are used to start and stop the resonant current flow at 1/4 wavelength intervals of the resonant frequency of the resonant tank formed by the external inductor and the array capacitors coupled to the column electrodes in order to form the pulses required to address the columns of the matrix. Switched current sources are used to start and stop nonresonant current flow to form the refresh and write pulses used to form the pulses required to address the rows of the matrix. Together, the pulses applied to the columns and rows of the matrix provide the high voltage necessary to light the EL pixels while minimizing the address time and power required to operate the EL display.

Embodiments of methods, apparatuses, devices and systems associated with a power management system are disclosed. In one such embodiment, a power management system includes a state machine, capable of transitioning the power management system to a safe state when an input signal and/or an output signal from a component of the power management system indicates occurrence of an error in the component.
