Section 22 Power-Down Modes
Section 22 Power-Down Modes
In the power-down modes, all CPU and some on-chip supporting module functions are halted.
This lowers power consumption.
The SH7706 has four power-down modes:
1. Sleep mode
2. Software standby mode
3. Module standby function (TMU, RTC, SCI, UBC, DMAC, DAC, ADC, and SCIF on-chip
supporting modules)
4. Hardware standby mode
Table 22.1 shows the transition conditions for entering the modes from the program execution
state, as well as the CPU and supporting module states in each mode and the procedures for
canceling each mode.
