Abstract:
1. A microcontroller for controlling a LCD, the microcontroller being mountable in any one of a plurality of package types, the microcontroller comprising: a LCD controller to generate logical mapping signals that indirectly code for voltages to be applied to electrodes of a LCD glass; a driver circuit to drive the electrodes; a remapping unit to receive the logical mapping signals from the LCD controller, wherein, in addition to an input to receive the logical mapping signals from the LCD controller, the remapping unit has inputs to receive, respectively (i) a package identifier indicative of the specified one of the package types, (ii) an indication of the number of LCD segment terminals to be used, and (iii) a vector describing which segment terminals are used for the particular package type, wherein the remapping unit is operable to map the logical mapping signals to the driver circuit, based on information received at each of the inputs, by converting, the logical mapping signals to enable signals and to physical segment data to be provided to the driver circuit.
