Type Definition lpc54606_pac::dma0::channel::xfercfg::W

type W = W<u32, XFERCFG>;

Writer for register XFERCFG

Methods

impl W

pub fn cfgvalid(&mut self) -> CFGVALID_W

Bit 0 - Configuration Valid flag. This bit indicates whether the current channel descriptor is valid and can potentially be acted upon, if all other activation criteria are fulfilled.

pub fn reload(&mut self) -> RELOAD_W

Bit 1 - Indicates whether the channel's control structure will be reloaded when the current descriptor is exhausted. Reloading allows ping-pong and linked transfers.

pub fn swtrig(&mut self) -> SWTRIG_W

Bit 2 - Software Trigger.

pub fn clrtrig(&mut self) -> CLRTRIG_W

Bit 3 - Clear Trigger.

pub fn setinta(&mut self) -> SETINTA_W

Bit 4 - Set Interrupt flag A for this channel. There is no hardware distinction between interrupt A and B. They can be used by software to assist with more complex descriptor usage. By convention, interrupt A may be used when only one interrupt flag is needed.

pub fn setintb(&mut self) -> SETINTB_W

Bit 5 - Set Interrupt flag B for this channel. There is no hardware distinction between interrupt A and B. They can be used by software to assist with more complex descriptor usage. By convention, interrupt A may be used when only one interrupt flag is needed.

pub fn width(&mut self) -> WIDTH_W

Bits 8:9 - Transfer width used for this DMA channel.

pub fn srcinc(&mut self) -> SRCINC_W

Bits 12:13 - Determines whether the source address is incremented for each DMA transfer.

pub fn dstinc(&mut self) -> DSTINC_W

Bits 14:15 - Determines whether the destination address is incremented for each DMA transfer.

pub fn xfercount(&mut self) -> XFERCOUNT_W

Bits 16:25 - Total number of transfers to be performed, minus 1 encoded. The number of bytes transferred is: (XFERCOUNT + 1) x data width (as defined by the WIDTH field). The DMA controller uses this bit field during transfer to count down. Hence, it cannot be used by software to read back the size of the transfer, for instance, in an interrupt handler. 0x0 = a total of 1 transfer will be performed. 0x1 = a total of 2 transfers will be performed. 0x3FF = a total of 1,024 transfers will be performed.
