Section 21 Power-Down State
21.1
Overview
The H8/3062 Series 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 21.1 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.
