Note 2-2: Relationship between tCYC and oscillation frequency is 3/FmCF at a division ratio of 1/1 and 6/FmCF at a division ratio of 1/2. Note 2-3: See Tables 1 and 2 for the oscillation constants. Note 2-4: An oscillation stabilization time of 100 s or longer must be provided before switching the system clock source after the state of the high-speed RC oscillation circuit is switched from “oscillation stopped” to “oscillation enabled” . |
