Description of Reset Operation
5.7.2.1
Reset Handshake Timing
The ITCN provides the 56800E core with a reset vector address on the VAB pins whenever RESET is
asserted from the SIM. The reset vector will be presented until the second rising clock edge after RESET
is released. The general timing is shown in Figure 5-22.

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.
