CHAPTER 8 LOW-POWER CONSUMPTION MODE

8.1 Overview of Low-Power Consumption Mode

The MB90360 series has the following CPU operating modes, any of which can be used

depending on operating clock selection and clock oscillation control:

• Clock mode : main clock mode, PLL clock mode, or sub-clock mode

• CPU intermittent operating mode : main clock intermittent operating mode, PLL clock

intermittent operating mode, or sub-clock intermittent

operating mode

• Standby mode : sleep mode, stop mode, watch mode, or timebase

timer mode

■ CPU Operating Modes and Current Consumption

Figure 8.1-1 shows the relationship between the CPU operating modes and current consumption.
