36.6.4 SLCDC Memory

Figure 36-10. Memory Management

When a bit in the display memory (SLCDC_LMEMRx) is written to ‘1’, the corresponding segment is energized (on), and non-energized when a bit in the display memory is written to ‘0’.

At the beginning of each common, the display buffer is updated. The value of the previous common is latched in the display memory (its value is transferred from the user buffer to the frame buffer).

The advantages of this solution are:

  • Ability to access the user buffer at any time in the frame, in any display mode and even in low-power waveform
  • Ability to change only one pixel without reloading the picture
