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.
Part 6 System Integration Module (SIM)
6.1 Introduction
The SIM module is a system catchall for the glue logic that ties together the system-on-chip. It controls
distribution of resets and clocks and provides a number of control features. The System Integration
Module’s functions are discussed in more detail in the following sections.
