DMA2D background PFC control register

Structs

• BGPFCCR_SPEC
  DMA2D background PFC control register
• R
  Register BGPFCCR reader
• W
  Register BGPFCCR 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 define which alpha channel value to be used for the background image. These bits can only be written when data transfers are disabled. Once the transfer has started, they are read-only. others: meaningless
• CCM_A
  CLUT Color mode These bits define the color format of the CLUT. This register 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 define the color format of the foreground image. These bits 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 is set to start the automatic loading of the CLUT. This bit is automatically reset: ** at the end of the transfer ** when the transfer is aborted by the user application by setting the ABORT bit in the DMA2D_CR ** when a transfer error occurs ** when the transfer has not started due to a configuration error or another transfer operation already on going (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 with the original alpha value according to the alpha mode selected with bits AM[1: 0]. These bits can only be written when data transfers are disabled. Once the transfer has started, they are 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 with the original alpha value according to the alpha mode selected with bits AM[1: 0]. These bits can only be written when data transfers are disabled. Once the transfer has started, they are read-only.
• AM_R
