Section 20 Power-Down Modes
Section 20 Power-Down Modes
In addition to the normal program execution state, this LSI has five power-down modes in which
operation of the CPU and oscillator is halted and power dissipation is reduced. Low-power
operation can be achieved by individually controlling the CPU, on-chip supporting modules, and
so on.
This LSI's operating modes are high-speed mode and five power down modes:
1. Medium-speed mode
2. Subactive mode
3. Sleep mode
4. Subsleep mode
5. Watch mode
6. Module stop mode
7. Software standby mode
8. Hardware standby mode
1. to 5. are power-down modes. Sleep mode is CPU states, medium-speed mode is a CPU and bus
master state, subactive mode is a CPU, bus master, and on-chip peripheral function state, and
module stop mode is an internal peripheral function (including bus masters other than the CPU)
state. Some of these states can be combined.
After a reset, the LSI is in high-speed mode, flash memory, and module stop mode (other than
DMAC).
Table 20.1 and table 20.2 show the LSI internal states in each mode and the transition conditions
of power-down modes respectively. Figure 20.1 shows the diagram of mode transition.
