2.6
This LSI has major three processing states: the reset state, instruction execution state, and power-
down state.
Reset State: In this state the CPU is reset. The reset state is divided into the power-on reset state
and the manual reset.
In the power-on reset state, the internal state of the CPU and the on-chip peripheral module
registers are initialized. In the manual reset state, the internal state of the CPU and some registers
of on-chip peripheral modules are initialized. For details, see register descriptions for each section.
Instruction Execution State: In this state, the CPU executes program instructions in sequence.
The Instruction execution state has the normal program execution state and the exception handling
state.
Power-Down State: In a power-down state, the CPU halts operation and power consumption is
reduced. The power-down state is entered by executing a SLEEP instruction. This LSI supports
sleep mode for the power-down state.
