#include <twl/mi.h>void MI_NDmaRestart( u32 ndmaNo );
| ndmaNo | DMA channel (0-3 within the new DMA) |
None.
Starts the new DMA once it has been configured.
This function starts DMA using the configuration of the current new DMA register. Specifically, it sets the enable bit of the new DMA specified by ndmaNo to 1. Other DMA-related registers must be set in advance.
DMA can be configured in advance with the MI_NDmaCopy*, MI_NDmaFill*, MI_NDmaClear*, MI_NDmaSend*, MI_NDmaRecv*, and MI_NDmaPipe* functions whose names include "_SetUp." For details, see the various function references.
Originally, this function was created to configure only the necessary registers and restart DMA after a DMA operation had completed. That is why this function includes "Restart" in its name.
Uses the new I/O DMA registers.
