21B.1 Overview
In addition to the normal program execution state, the H8S/2626 Group has nine 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/2626 operating modes are as follows:
(1) High-speed mode
(2) Medium-speed mode
(3) Subactive mode *
(4) Sleep mode
(5) Subsleep mode *
(6) Watch mode *
(7) Module stop mode
(8) Software standby mode
(9) Hardware standby mode
(2) to (9) are power-down modes. Sleep mode and sub-sleep mode are CPU states, medium-speed
mode is a CPU and bus master state, sub-active mode is a CPU and bus master and internal
peripheral function 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 are available in the H8S/2626 Group.
Table 21B.1 shows the internal state of the LSI in the respective modes. Table 21B.2 shows the
conditions for shifting between the power-down modes.
Figure 21B.1 is a mode transition diagram.
See section 20.7, Subclock Oscillator (H8S/2626 Group Only), for the method of fixing
pins OSC1 and OSC2 when not used.
