2.6.2
In this state the CPU executes program instructions.
2.6.3
The exception-handling state is a transient state that occurs when the CPU is reset or interrupted
and changes its normal processing flow. In interrupt exception handling, the CPU references the
stack pointer (R7) and saves the program counter and condition code register on the stack. For
further details see section 4, Exception Handling.
