7 Clock/Mode Control
Table 7-2 shows the warm-up time.

(Note)
PLL requires a certain amount of time to be stabilized, which should be secured using the warm-up
function.

warm-up time in consideration of the stability time of the PLL and the internal oscillator.
OSCCR0<WUEON><WUEF> is used to confirm the start and completion of warm-up through software

lowers the oscillator input frequency while increasing the internal clock speed.
This circuit outputs the fpll clock that is quadruple of the high-speed oscillator output clock, fosc. This
The PLL is disabled after reset is released. To enable the PLL, set "1" to the OSCCR0<WUEF> bit. The
The warm-up function secures the stability time for the oscillator and the PLL with the warm-up timer.
The warm-up function is used when returning from STOP/SLEEP mode. In this case, an interrupt for
In STOP/ SLEEP modes, the PLL is disabled. When returning from these modes, configure the
