Figure 2.16 shows the stack after exception handling ends.
2.8.4
In this state the CPU executes program instructions in sequence.
2.8.5
This is a state in which the bus has been released in response to a bus request from a bus master
other than the CPU. While the bus is released, the CPU halts except for internal operations.
There is one other bus master in addition to the CPU: the data transfer controller (DTC).
For further details, refer to section 6, Bus Controller.
2.8.6
The power-down state includes both modes in which the CPU stops operating and modes in which
the CPU does not stop. There are five modes in which the CPU stops operating: sleep mode,
software standby mode, hardware standby mode, subsleep mode, and watch mode. There are also
three other power-down modes: medium-speed mode, module stop mode, and subactive mode. In
medium-speed mode, the CPU and other bus masters operate on a medium-speed clock. Module
