DMA2D foreground PFC control register

Structs§

  • FGPFCCR_SPEC
    DMA2D foreground PFC control register
  • R
    Register FGPFCCR reader
  • W
    Register FGPFCCR writer

Enums§

  • AI_A
    Alpha Inverted This bit inverts the alpha value. Once the transfer has started, this bit is read-only.
  • AM_A
    Alpha mode These bits select the alpha channel value to be used for the foreground image. They can only be written data the transfer are disabled. Once the transfer has started, they become read-only. other configurations are meaningless
  • CCM_A
    CLUT color mode This bit defines the color format of the CLUT. It can only be written when the transfer is disabled. Once the CLUT transfer has started, this bit is read-only.
  • CM_A
    Color mode These bits defines the color format of the foreground image. They can only be written when data transfers are disabled. Once the transfer has started, they are read-only. others: meaningless
  • RBS_A
    Red Blue Swap This bit allows to swap the R & B to support BGR or ABGR color formats. Once the transfer has started, this bit is read-only.
  • START_A
    Start This bit can be set to start the automatic loading of the CLUT. It is automatically reset: ** at the end of the transfer ** when the transfer is aborted by the user application by setting the ABORT bit in DMA2D_CR ** when a transfer error occurs ** when the transfer has not started due to a configuration error or another transfer operation already ongoing (data transfer or automatic background CLUT transfer).

Type Aliases§

  • AI_R
    Field AI reader - Alpha Inverted This bit inverts the alpha value. Once the transfer has started, this bit is read-only.
  • AI_W
    Field AI writer - Alpha Inverted This bit inverts the alpha value. Once the transfer has started, this bit is read-only.
  • ALPHA_R
    Field ALPHA reader - Alpha value These bits define a fixed alpha channel value which can replace the original alpha value or be multiplied by the original alpha value according to the alpha mode selected through the AM[1:0] bits. These bits can only be written when data transfers are disabled. Once a transfer has started, they become read-only.
  • ALPHA_W
    Field ALPHA writer - Alpha value These bits define a fixed alpha channel value which can replace the original alpha value or be multiplied by the original alpha value according to the alpha mode selected through the AM[1:0] bits. These bits can only be written when data transfers are disabled. Once a transfer has started, they become read-only.
  • AM_R
    Field AM reader - Alpha mode These bits select the alpha channel value to be used for the foreground image. They can only be written data the transfer are disabled. Once the transfer has started, they become read-only. other configurations are meaningless
  • AM_W
    Field AM writer - Alpha mode These bits select the alpha channel value to be used for the foreground image. They can only be written data the transfer are disabled. Once the transfer has started, they become read-only. other configurations are meaningless
  • CCM_R
    Field CCM reader - CLUT color mode This bit defines the color format of the CLUT. It can only be written when the transfer is disabled. Once the CLUT transfer has started, this bit is read-only.
  • CCM_W
    Field CCM writer - CLUT color mode This bit defines the color format of the CLUT. It can only be written when the transfer is disabled. Once the CLUT transfer has started, this bit is read-only.
  • CM_R
    Field CM reader - Color mode These bits defines the color format of the foreground image. They can only be written when data transfers are disabled. Once the transfer has started, they are read-only. others: meaningless
  • CM_W
    Field CM writer - Color mode These bits defines the color format of the foreground image. They can only be written when data transfers are disabled. Once the transfer has started, they are read-only. others: meaningless
  • CSS_R
    Field CSS reader - Chroma Sub-Sampling These bits define the chroma sub-sampling mode for YCbCr color mode. Once the transfer has started, these bits are read-only. others: meaningless
  • CSS_W
    Field CSS writer - Chroma Sub-Sampling These bits define the chroma sub-sampling mode for YCbCr color mode. Once the transfer has started, these bits are read-only. others: meaningless
  • CS_R
    Field CS reader - CLUT size These bits define the size of the CLUT used for the foreground image. Once the CLUT transfer has started, this field is read-only. The number of CLUT entries is equal to CS[7:0]
  • CS_W
    Field CS writer - CLUT size These bits define the size of the CLUT used for the foreground image. Once the CLUT transfer has started, this field is read-only. The number of CLUT entries is equal to CS[7:0]
  • RBS_R
    Field RBS reader - Red Blue Swap This bit allows to swap the R & B to support BGR or ABGR color formats. Once the transfer has started, this bit is read-only.
