38.6.4.6 Layer Attributes Update Operation

A set of attribute configuration registers (LCDC_xxxCFGx, LCDC_xxxFBA and LCDC_xxxEN, where xxx indicates the layer) is dedicated to each layer and defines attributes specific to that layer. These registers can be updated by using the following procedure:

  1. Check that all fields in LCDC_ATTRS are cleared.
  2. Write the attribute configuration registers of each layer.
  3. Write a one to the Update Attribute field for each layer in LCDC_ATTRE.
