Chapter 4 MCU Control Function
4-1
4. MCU Control Function
4.1 Overview
The operating states of this LSI are classified into the following 4 modes including system reset mode:
(1)
System reset mode
(2)
Program run mode
(3)
HALT Mode
(4)
STOP mode
For system reset mode, see Chapter 3, “Reset Function”.
4.1.1 Features
•
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
supplies)
4.1.2 Configuration
Figure 4-1 shows an operating state transition diagram.
