CHAPTER 6: Low Power Consumption Mode
FM4 Peripheral Manual, Doc. No. 002-04856 Rev. *E 235
[bit1] WLVDI: LVD interrupt return bit
This bit indicates the CPU has returned from a deep standby mode due to the LVD interrupt.
The CPU has not returned from a deep standby mode due to the LVD interrupt. [initial value]
The CPU has returned from a deep standby mode due to the LVD interrupt.
[bit0] WRTCI: RTC interrupt return bit
This bit indicates the CPU has returned from a deep standby mode due to the RTC interrupt.
The CPU has not returned from a deep standby mode due to the RTC interrupt. [initial value]
The CPU has returned from a deep standby mode due to the RTC interrupt.
Notes:
− This register is initialized by the power-on reset and the low voltage detection reset. It is not
initialized by any reset other than the two mentioned before. In addition, reading this register
clears all its bits.
− This register can be set only in a deep standby mode.
− Please be sure to check that the return factor has not been set before making a transition to deep
standby mode. If the factor is set, please clear. ( include the interrupt pending register in the
NVIC)
