Table 5-4 shows transition of the CPU clock and examples of setting the SFR registers.
Notes 1. The CMC and OSMC registers can be written only once by an 8-bit memory manipulation instruction
Caution Set the clock after the supply voltage has reached the operable voltage of the clock to be set
Note The CMC register can be written only once by an 8-bit memory manipulation instruction after reset release.
Remark (A) to (I) in Table 5-4 correspond to (A) to (I) in Figure 5-15.
(The CPU operates with the internal high-speed oscillation clock immediately after a reset release (B).)
Remark ×: don’t care
(The CPU operates with the internal high-speed oscillation clock immediately after a reset release (B).)
