CHAPTER 6 LOW-POWER CONSUMPTION MODE
6.1

Outline of Low-Power Consumption Mode

The MB90330 series have the following CPU operation modes by selecting the operation
clock and operating the control of the clock.
• Clock mode
(PLL clock mode, main clock mode, and sub clock mode)
• CPU Intermittent operation mode
(PLL clock intermittent operation mode, main clock intermittent operation mode, and
sub clock intermittent operation mode)
• Standby mode
(sleep mode, timebase timer mode, and stop, watch mode)
CPU Operation Modes and Current Consumption
Figure 6.1-1 shows the relationships between the CPU operation modes and current consumption.
