Section 8 Power-Down Modes
8 . 1 Overview
In the power-down modes, all CPU and some on-chip supporting module functions are halted. This
lowers power consumption.
8 . 1 . 1 Power-Down Modes
The SH7708 Series have the following power-down modes:
1. Sleep mode
2. Standby mode
3. Module standby function (TMU, RTC, and SCI on-chip supporting modules)
4. Hardware standby mode (SH7708S, SH7708R only)
Table 8.1 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
