Table 7-4 shows transition of the CPU clock and examples of setting the SFR registers.
(The CPU operates with the internal high-speed oscillation clock immediately after a reset release (B).)
Notes 1. The clock operation mode control register (CMC) can be written only once by an 8-bit memory
Caution Set the clock after the supply voltage has reached the operable voltage of the clock to be set (see
