2.7.2
In the program execution state the CPU executes program instructions in sequence.
There are three modes in this state, two active modes (high speed and medium speed) and one
subactive mode. Operation is synchronized with the system clock in active mode (high speed and
medium speed), and with the subclock in subactive mode. See section 5, Power-Down Modes for
details on these modes.
2.7.3
In the program halt state there are four modes: sleep mode, standby mode, watch mode, and
subsleep mode. See section 5, Power-Down Modes for details on these modes.
2.7.4
The exception-handling state is a transient state occurring when exception handling is started by a
reset or interrupt and the CPU changes its normal processing flow. In exception handling caused
by an interrupt, SP (R7) is referenced and the PC and CCR values are saved on the stack.
For details on interrupt handling, see section 3, Exception Handling.
