Table 4-5 shows the wake-up time (restoring time) from the standby modes.
See Chapter 6 "Clock Generation Circuit" for details of the FHWUPT register.

[Note]
Ÿ
If SYSTEMCLK is switched to high-speed after the STOP/STOP-D mode is released and before the
high-speed clock wake-up time passes, the CPU must wait to run the program because the clock supply
is suspended until the end of the wake-up time.
Ÿ
If peripheral circuits need to work in the HALT-H mode, choose the low-speed clock for the operating
clock.
Ÿ
When the FHWUPT register is set to "0x00", the PLL output clock is masked for approx.2.5 ms. HSCLK
will be supplied after the elapse of 2.5 ms. If HSCLK is selected for SYSTEMCLK, the SYSTEMCLK is
stopped for the time period.
Ÿ
When the FHWUPT register is set to "0x01", the frequency of PLL oscillation clock gradually increases
from approx. 1 MHz after the elapse of the wake-up time chosen by the FHWUPT register and reaches the
target frequency (16 MHz/24 MHz) chosen by the code option before approx. 2 ms elapse. The PLL
oscillation clock during this time period can be used for the SYSTEMCLK, however, accuracy of the
frequency is not guaranteed.
