7.5
The sources of interrupts generated by the DMAC are transfer end and transfer break. Table 7.10
shows the interrupt sources and their priority order.
Table 7.10 Interrupt Source Priority Order
Enabling or disabling of each interrupt source is set by means of the DTIE bit for the
corresponding channel in DMABCR, and interrupts from each source are sent to the interrupt
controller independently. The relative priority of transfer end interrupts on each channel is decided
by the interrupt controller, as shown in table 7.10.
Figure 7.24 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 DTE bit is cleared to 0.
In full address mode, a transfer break interrupt is generated when the DTME bit is cleared to 0
while DTIEB 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.
