STOP mode
In this mode, all the operations in the system, including the oscillation circuits, are stopped and the
In the STOP mode, the peripheral circuits stop in the states when the STOP mode is activated or become
The STOP mode is activated by setting SYSCR1<STOP> to "1".
The STOP mode is released by the STOP mode release signals. After the warm-up time has elapsed, the
