ABSTRACT:
A digital controller comprises a register containing control bits and (b) an input node coupled to the register, wherein a first signal at the input node changes a first pattern of the control bits into (i) a second pattern of the control bits when a time interval between the first signal and an immediately preceding second signal is greater than a first time interval or (ii) into a third pattern of the control bits differing from the second pattern when the time interval is less than a second time interval which is less than the first time interval. The register is electrically coupled to a counter, which counts at a variable rate. The control bits controls the variable rate at which the counter counts. A second signal may also selectably change the second pattern of control bits to be changed to a fourth pattern of control bits or the third pattern of control bits to be changed to the fourth pattern of control bits. The fourth pattern of control bits causes the counter to change the direction the counter is counting. The counter preferably varies a resistance of a resistor coupled between a power source and an output to control audio of an audio system and/or to control brightness of light emitted from a light source.
