Section 6 Interrupt Controller (INTC)
6.6.1
1. Either do not select the DMAC as a source, or clear the DME bit to 0.
2. Activating sources are applied to the CPU when interrupts occur.
3. The CPU clears interrupt sources with its interrupt processing routine and performs the
6.6.2
1. Select the DMAC as a source and set the DME bit to 1. CPU interrupt sources are masked
2. Activating sources are applied to the DMAC when interrupts occur.
3. The DMAC clears activating sources at the time of data transfer.
