There are two ways to bring a channel out of pause and into active mode:
- Keep the current state and read the next descriptor continuously from the last
descriptor before going into pause.
- CONT bit is set in the control register and [CONT_ADDR] = 0.
- Use the DSCR start address to fetch the first descriptor coming out of pause.
- CONT bit is set in the control register and [CONT_ADDR] = 1.
Software can also put the DMA channel in disable mode from pause mode: Mode = Pause, enable = 0, and [CONT] = 1.
