14.4 Interrupt Sources
This module has three interrupt signals. Table 14.4 shows the interrupt sources and their
corresponding interrupt request signals. The EXIRQ interrupt signals are activated at low level.
The EXIRQ interrupt requests can only be detected at low level (specified as level sensitive). The
suspend/resume interrupt request IRQ6 must be specified to be detected at the falling edge (falling-
edge sensitive) by the interrupt controller register.
