Abstract
A method and apparatus provide an ability to selectively couple one of the output of the buffer or the output of the digital driver to a data terminal based upon a state of a storage location in which a stored first select indicator is stored and based upon a state of a selection signal. An external serial interface, at a semiconductor die, includes the data terminal, a selection terminal to receive the selection signal, and a clock terminal to receive a clock signal. A buffer includes an input to receive a secondary signal and an output to provide the secondary signal to the data terminal. A digital driver includes a digital output coupled to the data terminal. A first storage location has a storage state based upon the stored first select indicator. Select circuitry provides the selectively coupling.
