Abstract:
1. A method comprising: (a) in a first mode disabling a keypress entry interface of an integrated circuit and enabling a pass-through data path, wherein the pass-through data path extends from a display information input interface of the integrated circuit and passes through the integrated circuit and to a display information output interface of the integrated circuit, wherein untrusted information is displayed and wherein untrusted information is received from an unauthorized source; and (b) in a second mode enabling the keypress entry interface and disabling the pass-through data path such that information received onto the display information input interface cannot pass through the pass-through data path to the display information output interface, wherein trusted information is displayed and wherein trusted information is received from an authorized source, and wherein the first and second modes are two modes of operation of the integrated circuit.
