5.1
The H8/3834 Series has seven modes of operation after a reset. These include six power-down
modes, in which power dissipation is significantly reduced.
Table 5.1 gives a summary of the seven operation modes.

Standby mode
All the above operating modes except active (high-speed) mode are referred to as power-down
modes.
In this section the two active modes (high-speed and medium-speed) are referred to collectively as
active mode.
Figure 5.1 shows the transitions among these operation modes. Table 5.2 indicates the internal
states in each mode.

Description
The CPU runs on the system clock, executing program
instructions at high speed
The CPU runs on the system clock, executing program
instructions at reduced speed
The CPU runs on the subclock, executing program instructions
at reduced speed
The CPU halts. On-chip peripheral modules continue to
operate on the system clock.
The CPU halts. Timer A, timer C, timer G, and the LCD
controller/driver continue to operate on the subclock.
The CPU halts. The time-base function of timer A and the LCD
controller/driver continue to operate on the subclock.
The CPU and all on-chip peripheral modules stop operating
