Table 6 - 7 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)
(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 13.8 SNOOZE Mode
Function , 14.5.7 Calculating transfer clock frequency , and 14.6.3 Calculating baud rate .
Remark (A) to (J) in Tables 6 - 3 to 6 - 7 correspond to (A) to (J) in Figure 6 - 19.
