pub struct R(/* private fields */);

Register FGPFCCR reader

Implementations

impl R

pub fn cm(&self) -> FieldReaderRaw<u8, CM_A>

Bits 0:3 - 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

pub fn ccm(&self) -> BitReaderRaw<CCM_A>

Bit 4 - 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.

pub fn start(&self) -> BitReaderRaw<START_A>

Bit 5 - 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).

pub fn cs(&self) -> FieldReaderRaw<u8, u8>

Bits 8:15 - 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]

pub fn am(&self) -> FieldReaderRaw<u8, AM_A>

Bits 16:17 - 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

pub fn css(&self) -> FieldReaderRaw<u8, u8>

Bits 18:19 - 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

pub fn ai(&self) -> BitReaderRaw<AI_A>

Bit 20 - Alpha Inverted This bit inverts the alpha value. Once the transfer has started, this bit is read-only.

pub fn rbs(&self) -> BitReaderRaw<RBS_A>

Bit 21 - 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.

pub fn alpha(&self) -> FieldReaderRaw<u8, u8>

Bits 24:31 - 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.

Methods from Deref<Target = R<FGPFCCR_SPEC>>
