• Description: Hardware Manual
• Manufacturer: Hitachi Semiconductor

20.1
This chip has a module standby function (which reduces power consumption by selectively halting
operation of unnecessary modules among the on-chip peripheral modules and the DSP unit), a
sleep mode (which halts CPU functions), and a standby mode (which halts all functions).
20.1.1
The following modes and function are provided as power-down modes:
1. Sleep mode
2. Standby mode
3. Module standby function
Table 20.1 shows the transition conditions for entering the modes from the program execution
state, as well as the CPU and peripheral module states in each mode and the procedures for
canceling each mode.
