CHAPTER 6 LOW-POWER CONSUMPTION MODE

6.1 Outline of Low-Power Consumption Mode

6.1 Outline of Low-Power Consumption Mode
The MB90335 series have the following CPU operation modes by selecting the operation
clock and operating the control of the clock.
• Clock mode
(PLL clock mode and main clock mode)
• CPU Intermittent operation mode
(PLL clock intermittent operation mode and main clock intermittent operation mode)
• Standby mode
(sleep mode, time-base timer mode, and stop mode)
■ CPU Operation Modes and Current Consumption
Figure 6.1-1 shows the relationships between the CPU operation modes and current consumption.
