Assembler syntax
DMAFLUSHP <peripheral>
where:
<peripheral> 5-bit immediate, value 0-31
Operation
You can only use this instruction in a DMA channel thread.
DMAGO
When the DMA manager executes Go for a DMA channel that is in the Stopped state, it performs the
following steps on the DMA channel:
1. Moves a 32-bit immediate into the program counter
2. Sets its security state
3. Updates it to the Executing state.
Note: If a DMA channel is not in the Stopped state when the DMA manager executes DMAGO then the
DMAC does not execute DMAGO but instead it executes DMANOP.
