CHAPTER 6: Low Power Consumption Mode
FM4 Peripheral Manual, Doc. No. 002-04856 Rev. *E 241
9. Usage Precautions
Note the following when using the low power consumption mode
For a pin shared between analog input and WKUP, if the ADE bit in the Analog Input Setting Register
(ADE) is set to 1, the WKUPx pin input is blocked, even when the CPU returning from a deep standby
mode due to the WKUPx pin input is enabled. To enable the CPU to return from a deep standby mode
due to the WKUPx pin input, write 0 to the ADE bit in the Analog Input Setting Register (ADE) before
making the CPU transit to a deep standby mode.
