Section 5 Interrupt Controller (INTC)
5.9
Interrupt request signals can be used to activate the DMAC and transfer data.
Interrupt sources that are designated to activate the DMAC are masked without being input to the
INTC. The mask condition is as follows:
Figure 5.13 shows a block diagram of interrupt control.
Here, DME is bit 0 in DMAOR of the DMAC, and DEn (n = 0 to 7) is bit 0 in CHCR0 to CHCR7
of the DMAC. For details, see section 9, Direct Memory Access Controller (DMAC).
