Section 13
Immediately after an interrupt is detected, the phase of the clock output of the CKIO pin may be
unstable, until software standby mode is canceled.
Notes: 1. Only when the RTC is used, software standby mode can be canceled by IRQ (edge
(2)
Software standby mode is canceled by a reset with the RESETP pin and RESETM pin. Keep the
RESETP pin and RESETM pin low until the clock oscillation settles in clock operating mode to
use PLL. The internal clock will continue to be output to the CKIO pin.
