State 1
Operation clock source:
f(XIN) (Note 1)
f(XIN) oscillation enabled
Ring oscillator stop
State 2
Operation clock source:
f(XIN) (Note 1)
f(XIN) oscillation enabled
Ring oscillator enabled
State 3
Operation clock source:
Ring oscillator (Note 3)
f(XIN) oscillation enabled
Ring oscillator enalbed
State 4
Operation clock source:
Ring oscillator (Note 3)
f(XIN) oscillation stop
Ring oscillator enalbed
Notes on switch of clock
(1) In operation clock source = f(XIN), the following can be
selected for the CPU clock division ratio.
q f(XIN)/2 (high-speed mode)
q f(XIN)/8 (middle-speed mode)
q f(XIN) (double-speed mode, only at a ceramic oscillation)
(2) Execute the state transition state 3 to state 2 or
state 3’ to state 2’ after stabilizing XIN oscillation.
(3) In operation clock source = ring oscillator, the middle-
speed mode is selected for the CPU clock division ratio.
(4) When the state transition state 2
→ state 3 → state 4
is performed, execute the NOP instruction as shown below
according to the division ratio of CPU clock.
CPUM76
→ 102 (State 2 → state 3)
NOP instruction
CPUM4
→ 12 (State 3 → state 4)
Double-speed mode at ring oscillator: NOP 3
High-speed mode at ring oscillator: NOP 1
Middle-speed mode at ring oscillator: NOP 0
