<p>This document discloses display controller embodiments which comprise a first set of registers to hold data to be displayed and a second set of registers loadable from the first set of registers. A set of multiplexers has first data inputs coupled to the first set of registers, second data inputs coupled to the second set of registers, and select inputs. Logic circuitry is coupled to the output of the set of multiplexers and to the control inputs of the multiplexers, the control circuitry providing select information to the select inputs of the set of multiplexers and providing waveforms to the display panel to selectively display data from the first set of registers and the second set of registers in accordance with the select information. Other embodiments and methods are also disclosed.</p>
