Section 24 Power-Down Modes
Section 24 Power-Down Modes
In addition to the normal program execution state, this LSI has nine 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 peripheral modules, and
so on.
This LSI operating modes are as follows:
1. High-speed mode
2. Medium-speed mode
3. Subactive mode
4. Sleep mode
5. Subsleep mode
6. Watch mode
7. Module stop mode
8. Software standby mode
9. Hardware standby mode
2. to 9. are low power dissipation states. Sleep mode and subsleep mode are CPU states, medium-
speed mode is a CPU and bus master state, subactive mode is a CPU and bus master and internal
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 with modules other than the DTC in module stop
mode.
Table 24.1 shows the internal state of the LSI in the respective modes. Table 24.2 shows the
conditions for shifting between the low power dissipation modes.
Figure 24.1 is a mode transition diagram.
