Table 8.3 lists the Setting Clock Related Bit and Modes.
1. When the CM05 bit is set to 1 (main clock turned off) in low-speed mode, the mode goes to low power
2. The divide-by-n value can be selected the same way as in on-chip oscillator mode.
The on-chip oscillator clock divided by 1 (undivided), 2, 4, 8 or 16 provides the CPU clock. The on-chip
oscillator clock is also the clock source for the peripheral function clocks. If the sub clock is on, fC32 can
be used as the count source for timers A and B. When the operating mode is returned to the high-speed
and medium-speed modes, set the CM06 bit in the CM0 register to 1 (divide-by-8 mode).
The main clock is turned off after being placed in on-chip oscillator mode. The CPU clock can be
selected as in on-chip oscillator mode. The on-chip oscillator clock is the clock source for the peripheral
function clocks. If the sub clock is on, fC32 can be used as the count source for timers A and B.
dissipation mode and the CM06 bit is set to 1 (divide-by-8 mode) simultaneously.
