21.1
In addition to the normal program execution state, the H8S/2357 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/2357 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/2357 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.
Table 21-1 Operating Modes
Notes: 1. The bus master operates on the medium-speed clock, and other on-chip supporting modules on the high-speed
2. The SCI and A/D converter are reset, and other on-chip supporting modules retain their state.
