1. A mobile telephone comprising:
- an event-sensitive panel having a plurality of sensors for providing feedback indicative of an event or no-event condition on the panel; and
channel scan logic configured to generate timing sequences and sensor address information for autonomously scanning at least some of the plurality of sensors substantially free of intervention from a processor.

Abstract
A device that can autonomously scan a sensor panel is disclosed. Autonomous scanning can be performed by implementing channel scan logic. In one embodiment, channel scan logic carries out many of the functions that a processor would normally undertake, including generating timing sequences and obtaining result data; comparing scan result data against a threshold value (e.g., in an auto-scan mode); generating row count; selecting one or more scanning frequency bands; power management control; and performing an auto-scan routine in a low power mode.
