The maximum transfer rate is calculated from the fact that 16 bits are moved every 8 clocks.
The calculation is as follows:
The IDMA controller block diagram is shown in Figure 3-1.
3.1.2 IDMA Registers (Independent DMA Controller)
The IDMA has six registers that define its specific operation. These registers include a 32-
bit source address pointer register (SAPR), a 32-bit destination address pointer register
