change the priority queue. This register is not reinitialized to its initial value if round-robing
scheduling is disabled, so if default static priority is needed the register must be written to zero.
• Bit 7 - RREN: Round-robin Scheduling Enable
When the RREN bit is set the round-robin scheduling scheme is enabled for low level interrupts.
When this bit is cleared, the priority is static according to interrupt vector address where the low-
est address has the highest priority.
• Bit 6 - IVSEL: Interrupt Vector Select
When the IVSEL bit is cleared (zero), the interrupt vectors are placed at the start of the Applica-
tion section in flash. When this bit is set (one), the interrupt vectors are moved to the beginning
of the Boot section of the Flash. Refer to the device data sheet for the absolute address.
This bit is protected by the Configuration Change Protection mechanism, refer to
”Configuration Change Protection” on page 12
• Bit 5:3 - Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always
write these bits to zero when this register is written.
• Bit 2 - HILVLEN: High Level Interrupt Enable
When this bit is set all high level interrupts are enabled. If this bit is cleared, high level interrupt
requests will be ignored.
• Bit 1 - MEDLVLEN: Medium Level Interrupt Enable
When this bit is set all medium level interrupts are enabled. If this bit is cleared, medium level
interrupt requests will be ignored.
• Bit 0 - LOLVLEN: Low Level Interrupt Enable
When this bit is set all low level interrupts are enabled. If this bit is cleared, low level interrupt
requests will be ignored.
