Section 7 DMA Controller (DMAC)
7.6
The sources of interrupts generated by the DMAC are transfer end and transfer break. Table 7.12
shows the interrupt sources and their priority order.
Table 7.12 Interrupt Sources and Priority Order
Enabling or disabling of each interrupt source is set by means of the DTIE bit in DMABCRL for
the corresponding channel in DMABCRL, and interrupts from each source are sent to the interrupt
controller independently. The priority of transfer end interrupts on each channel is decided by the
interrupt controller, as shown in table 7.12.
Figure 7.38 shows a block diagram of a transfer end/transfer break interrupt. An interrupt is
always generated when the DTIE bit is set to 1 while the DTE bit in DMABCRL is cleared to 0.
In full address mode, a transfer break interrupt is generated when the DTME bit is cleared to 0
while the DTIE bit is set to 1. In both short address mode and full address mode, DMABCR
should be set so as to prevent the occurrence of a combination that constitutes a condition for
interrupt generation during setting.
