Figure 5-3 shows the timing of the setting of the interrupt flags (IRQnF).
Interrupts IRQ
whether the corresponding pin is set for input or output. When using a pin for external interrupt
input, clear its DDR bit to 0 and do not use the pin for chip select output, refresh output, or SCI
input or output.
5.3.2 Internal Interrupts
Thirty-four internal interrupts are requested from the on-chip supporting modules.

5.3.3 Interrupt Vector Table
Table 5-3 lists the interrupt sources, their vector addresses, and their default priority order. In the
default priority order, smaller vector numbers have higher priority. The priority of interrupts other
than NMI can be changed in IPRA and IPRB. The priority order after a reset is the default order
shown in table 5-3.
Each on-chip supporting module has status flags for indicating interrupt status, and enable
bits for enabling or disabling interrupts.
Interrupt priority levels can be assigned in IPRA and IPRB.
ITU and SCI interrupt requests can activate the DMAC, in which case no interrupt request is
sent to the interrupt controller, and the I and UI bits are disregarded.
