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
high or HLCLK bit is “0”, but CKS2~CKS0 is set to “010”, “011”, “100”, “101”, “110” or “111”.
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.
