5.5 Operating Modes
The ITCN module design contains two major modes of operation:
Functional Mode
The ITCN is in this mode by default.
Wait and Stop Modes
During Wait and Stop modes, the system clocks and the 56800E core are turned off. The ITCN will signal
a pending IRQ to the System Integration Module (SIM) to restart the clocks and service the IRQ. An IRQ
can only wake up the core if the IRQ is enabled prior to entering the Wait or Stop mode.
5.6 Register Descriptions
A register address is the sum of a base address and an address offset. The base address is defined at the
