Section 21A Power-Down Modes
[H8S/2623 Group]
Subclock functions are not available in the H8S/2623 Group.
21A.1 Overview
In addition to the normal program execution state, the H8S/2623 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/2623 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
(2) to (6) are power-down modes. Sleep mode is CPU states, medium-speed mode is a CPU and
bus master state, and module stop mode is an internal peripheral function (including bus masters
other than the CPU) state. Some of these states can be combined.
After a reset, the LSI is in high-speed mode with modules other than the DTC in module stop
mode.
Note: Subclock functions (subactive mode, subsleep mode, and watch mode) are not available in
the H8S/2623 Group.
Table 21A.1 shows the internal state of the LSI in the respective modes.
Figure 21A.1 is a mode transition diagram.
