Abstract
A method for providing debounce and jog control for a keyboard includes loading a first electronic storage register with a value indicative of a debounce period for the keyboard and loading a second electronic storage register with a value indicative of a jog period for the keyboard. The keyboard is scanned for a pressed key, and a signal indicative of the pressed key is debounced. The method further includes providing electronic signals for key status and jog and asserting an interrupt in accordance with the indicated debounce period and the indicated jog period while the debounced signal indicates the pressed key is down. Keys of the keyboard other than the pressed key are prevented from being scanned until the debounced signal indicates that the pressed key has come up.
