5.4.2 Internal Interrupts
Internal interrupts issued from the on-chip peripheral modules have the following features:
• For each on-chip peripheral module there are flags that indicate the interrupt request status,
and enable bits that individually select enabling or disabling of these interrupts. When the
enable bit for a particular interrupt source is set to 1, an interrupt request is sent to the interrupt
controller.
• The control level for each interrupt can be set by ICR.
• The DTC can be activated by an interrupt request from an on-chip peripheral module.
• An interrupt request that activates the DTC is not affected by the interrupt control mode or the
status of the CPU interrupt mask bits.
