Note
Oscillation of internal high-speed oscillator
and selection of internal high-speed
oscillation clock as main system clock
• HIOSTOP = 0, MCS = 0
Stabilization of X1 oscillation and selection
of high-speed system clock as main system
clock
• OSCSEL = 1, EXCLK = 0, MSTOP = 0
• After elapse of oscillation stabilization time
• MCS = 1
Enabling input of external clock from the
EXCLK pin and selection of high-speed
system clock as main system clock
• OSCSEL = 1, EXCLK = 1, MSTOP = 0
• MCS = 1
Transition cannot be performed unless the
clock is changed to the internal high-speed
oscillation clock once.
• SELDSC = 0
Transition cannot be performed unless the
clock is changed to the internal high-speed
oscillation clock once.
Transition cannot be performed unless the
clock is changed to the internal high-speed
oscillation clock once.
Transition cannot be performed unless the
clock is changed to the internal high-speed
oscillation clock once.
(Set when changing the clock.)
