6. Interrupt Controller (INTC)
6.8
The following data transfers can be done using interrupt request signals:
• Activate DMAC only, CPU interrupts do not occur
• Activate DTC only, CPU interrupts according to DTC settings
Interrupt sources that are activated by DMAC are masked without being input to INTC. Mask
condition is as follows:
Mask condition = DME • (DE0 • interrupt source select 0 + DE1 • interrupt source select 1 + DE2
The INTC masks CPU interrupts when the corresponding DTE bit is 1. The conditions for clearing
DTE and interrupt source flag are listed below.
Figure 6.6 shows a control block diagram.

DTE clear condition = DTC transfer end • DTECLR
Interrupt source flag clear condition = DTC transfer end • DTECLR+DMAC transfer end
Where: DTECLR = DISEL + counter 0.
