Table 5-3. CPU Clock Transition and SFR Register Setting Examples (5/5)
(11) • STOP mode (H) set while CPU is operating with high-speed on-chip oscillator clock (B)
• STOP mode (I) set while CPU is operating with high-speed system clock (C)
(Setting sequence)
Status Transition Setting
(B) → (H) Stopping peripheral
functions that cannot
operate in STOP mode
−
Executing STOP
instruction
(C) → (I) In X1 oscillation
Sets the OSTS
register
External main
system clock
−
(12) CPU changing from STOP mode (H) to SNOOZE mode (J)
For details about the setting for switching from the STOP mode to the SNOOZE mode, see 11.8 SNOOZE Mode
Function, 12.5.7 SNOOZE mode function and 12.6.3 SNOOZE mode function.
Remark (A) to (J) in Table 5-3 correspond to (A) to (J) in Figure 5-15.
