Operation clock source: On-chip oscillator (Note 2)
Operation clock source: f(XIN) (Note 1)
Notes on switch of clock
(1) In operation clock = f(XIN), the following can be selected for the CPU clock division ratio.
f(XIN)/2 (high-speed mode)
f(XIN)/8 (middle-speed mode)
f(XIN) (double-speed mode, only at a ceramic oscillation)
(2) In operation clock = On-chip oscillator, the following can be selected for the CPU clock division ratio.
ROSC/1 (On-chip oscillator double-speed mode)
ROSC/2 (On-chip oscillator high-speed mode)
ROSC/8 (On-chip oscillator middle-speed mode)
ROSC/128 (On-chip oscillator low-speed mode)
(3) After system is released from reset, and state transition of state 2 → state 3 and state transition of state 2’ → state 3’,
ROSC/8 (On-chip oscillator middle-speed mode) is selected for CPU clock.
(4) Executing the state transition state 3 to 2 or state 3’ to 2’ after stabilizing XIN oscillation.
(5) When the state 2 → state 3 → state 4 is performed, execute the NOP instruction as shown below
according to the division ratio of CPU clock.
1. CPUM76 = 102 (state 2 → state 3)
2. NOP instruction
Transition from Double-speed mode: NOP 3
Transition from High-speed mode: NOP 1
Transition from Middle-speed mode: NOP 0
3. CPU4 = 12 (state 3 → state 4)
(6) When the state 3 → state 2 → state 1 is performed, execute the NOP instruction as shown below
according to the division ratio of CPU clock.
1. CPUM76 = 002 or 012 or 112 (state 3 → state 2)
2. NOP instruction
Transition from On-chip oscillator double-speed mode: NOP 4
Transition from On-chip oscillator high-speed mode: NOP 2
Transition from On-chip oscillator middle-speed mode: NOP 0
Transition from On-chip oscillator low-speed mode: NOP 0
