Transition of normal mode
Main clock is oscillating
Sub clock is stopped
Medium-speed mode
(divided-by-8 mode)
CM06 = “1”
BCLK : f(XIN)/8
CM07 = “0” CM06 = “1”
Main clock is oscillating CM04 = “0”
Sub clock is oscillating
CM04 = “1”
(Notes 1, 3)

(divided-by-16 mode)
BCLK : f(XIN)/16
CM07 = “0” CM06 = “0”
CM17 = “1” CM16 = “1”
Main clock is stopped
Sub clock is oscillating
Low power dissipation mode
CM07 = “1” (Note 2)
CM05 = “1”
BCLK : f(XCIN)
CM07 = “1”
CM07 = “0” (Note 1)
CM06 = “0” (Note 3)
CM04 = “1”
Note 1: Switch clock after oscillation of main clock is sufficiently stable.
Note 2: Switch clock after oscillation of sub clock is sufficiently stable.
Note 3: Change CM06 after changing CM17 and CM16.
Note 4: Transit in accordance with arrow.
