impl Fgpfccr

pub const fn cm(&self) -> FgpfccrCm

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 set_cm(&mut self, val: FgpfccrCm)

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 const fn ccm(&self) -> FgpfccrCcm

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 set_ccm(&mut self, val: FgpfccrCcm)

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 const fn start(&self) -> FgpfccrStart

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 set_start(&mut self, val: FgpfccrStart)

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 const fn cs(&self) -> u8

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 set_cs(&mut self, val: u8)

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 const fn am(&self) -> FgpfccrAm

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 set_am(&mut self, val: FgpfccrAm)

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 const fn css(&self) -> u8

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 set_css(&mut self, val: u8)

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 const fn ai(&self) -> FgpfccrAi

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

pub fn set_ai(&mut self, val: FgpfccrAi)

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

pub const fn rbs(&self) -> FgpfccrRbs

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 set_rbs(&mut self, val: FgpfccrRbs)

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 const fn alpha(&self) -> u8

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.

pub fn set_alpha(&mut self, val: u8)

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.
