Enum lpc845_pac::dma0::channel::cfg::TRIGTYPE_A [−][src]
pub enum TRIGTYPE_A {
EDGE,
LEVEL,
}
Expand description
Trigger Type. Selects hardware trigger as edge triggered or level triggered.
Value on reset: 0
Variants
0: Edge. Hardware trigger is edge triggered. Transfers will be initiated and completed, as specified for a single trigger.
1: Level. Hardware trigger is level triggered. Note that when level triggering without burst (BURSTPOWER = 0) is selected, only hardware triggers should be used on that channel. Transfers continue as long as the trigger level is asserted. Once the trigger is de-asserted, the transfer will be paused until the trigger is, again, asserted. However, the transfer will not be paused until any remaining transfers within the current BURSTPOWER length are completed.
