18. Power-Down State
Section 18 Power-Down State
18.1
Overview
The H8/3008 has a power-down state that greatly reduces power consumption by halting the CPU,
and a module standby function that reduces power consumption by selectively halting on-chip
modules.
The power-down state includes the following three modes:
• Sleep mode
• Software standby mode
• Hardware standby mode
The module standby function can halt on-chip supporting modules independently of the power-
down state. The modules that can be halted are the 16-bit timer, 8-bit timer, SCI0, SCI1, and A/D
converter.
Table 18.1 indicates the methods of entering and exiting the power-down modes and module
standby mode, and gives the status of the CPU and on-chip supporting modules in each mode.
