Note 2-1: Relationship between tCYC and oscillation frequency is 3/FmMRC at a division ratio of 1/1 and 6/FmMRC

at a division ratio of 1/2.

Note 2-2: When switching the system clock, allow an oscillation stabilization time of 100

s or longer after the

High-speed RC oscillator circuit transmits from the "oscillation stopped" to "oscillation enabled" state.
