CHAPTER 6 LOW POWER CONSUMPTION MODE
6.1 Low Power Consumption Mode
F
2
MC-16LX microcontrollers have the following CPU operating modes, any of which can
be used depending on the operating clock selection and clock operation control:
• 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, time-base timer and stop modes)
All modes other than PLL clock mode are low power consumption mode.
