4.1
4.1.1
• HALT mode, where the CPU stops operating and only the peripheral circuit is operating
• STOP mode, where both low-speed oscillation and high-speed oscillation stop
• Stop code acceptor function, which controls transition to STOP mode
• Block control function, which power downs the circuits of unused peripherals (reset registers and stop clock
4.1.2
The operating states of this LSI are classified into the following 4 modes including system reset mode:
System reset mode
Program run mode
HALT mode
STOP mode
For system reset mode, see Chapter 3, “Reset Function”.
This LSI has a block control function, which power downs the circuits of unused peripherals (reset registers and stop
clock supplies) to make even more reducing the current consumption.
Figure 4-1 shows an operating state transition diagram.
