5.6.32.5
This field is used to set the interrupt priority level for IRQs. This IRQ is limited to priorities 0 through 2.
They are disabled by default.
5.7 Resets
5.7.1
The ITCN provides the 56800E core with a reset vector address whenever RESET is asserted. The reset
vector will be presented until the second rising clock edge after RESET is released.
5.7.2
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:
These interrupts are enabled at their fixed priority levels.
