Introduction
5.7.3 ITCN After Reset
After reset, all of the ITCN registers are in their default states. This means all interrupts are disabled,
except the core IRQs with fixed priorities:
⢠Illegal Instruction
⢠SW Interrupt 3
⢠HW Stack Overflow
⢠Misaligned Long Word Access
⢠SW Interrupt 2
⢠SW Interrupt 1
⢠SW Interrupt 0
⢠SW Interrupt LP
These interrupts are enabled at their fixed priority levels.
