Enhanced I/O Flash Type MCU
SLOW Mode to NORMAL Mode Switching
In SLOW Mode the system uses the LIRC low speed system oscillator. To switch back to the
NORMAL Mode, where the high speed system oscillator is used, the HLCLK bit should be set to ²1²
or HLCLK bit is ²0² but CKS2~CKS0 is set to 010B, 011B, 100B, 101B, 110B or 111B. As a certain
amount of time will be required for the high frequency clock to stabilise, the status of the HTO bit is
checked. The amount of time required for high speed system oscillator stabilization depends upon
which high speed system oscillator type is used.
