17.1 Overview
The H8/3002 has a power-down state that greatly reduces power consumption by halting CPU
functions. The power-down state includes the following three modes:
•
•
•
Table 17-1 indicates the methods of entering and exiting these power-down modes and the status
of the CPU and on-chip supporting modules in each mode.
