Section 21 Power-Down Modes
21.1
Overview
In addition to the normal program execution state, the H8S/2655 Group has five power-down
modes in which operation of the CPU and oscillator is halted and power dissipation is reduced.
Low-power operation can be achieved by individually controlling the CPU, on-chip supporting
modules, and so on.
The H8S/2655 Group operating modes are as follows:
(1) High-speed mode
(2) Medium-speed mode
(3) Sleep mode
(4) Module stop mode
(5) Software standby mode
(6) Hardware standby mode
Of these, (2) to (6) are power-down modes. Sleep mode is a CPU mode, medium-speed mode is a
CPU and bus master mode, and module stop mode is an on-chip supporting module mode
(including bus masters other than the CPU). A combination of these modes can be set.
After a reset, the H8S/2655 Group is in high-speed mode.
Table 21.1 shows the conditions for transition to the various modes, the status of the CPU, on-chip
supporting modules, etc., and the method of clearing each mode.
