Point C The GPIO01 pin sets to a logic 1 and causes the HIB_MODE pin to set to a logic 1. This causes

as soon as software writes the target time register to 0x0000_0005. The external RTC wakeup source pin,
GPIO01, asserts. As soon as this pin asserts, the corresponding bit in the RTC keep alive register is set.
Likewise, when GPIO02 and GPIO03 are set, their corresponding bits, WU_SRC_2 and WU_SRC_3 are
also set. If the system software accesses the RTC Keep Alive Register (RTC_KAR) and more than one of
the wakeup bits is set, it is not possible to see which one occurred first. On the other hand, any time that
one of the six external RTC wakeup pins asserts, that occurrence is recorded in the RTC keep alive register.
Recall that the WU_SRC_x bits are sticky bits and does not return to a logic 0 until a logic 1 is written to
their respective bit position in the RTC keep alive register.
27.4.5.2
As shown in
as soon as software writes the target time register to 0x0000_0005. The external RTC wakeup source pin,
GPIO01, asserts. As soon as this pin asserts, the corresponding bit in the RTC Keep Alive Register
(RTC_KAR) is set; however, when GPIO02 and GPIO03 are set after GPIO01 is set and remains set, the
WU_SRC_2 and WU_SRC_3 are not set. In this case, once an external RTC wakeup source is asserted
and the corresponding bit in the RTC Keep Alive Register (RTC_KAR) is set, no more bits are set in the
RTC keep alive register by asserting additional external RTC wakeup pins until the first external interrupt
source is negated and its corresponding flag in the RTC Keep Alive Register (RTC_KAR) is also negated
by writing a logic 1 to its bit position. This methodology allows the system software to determine which
external wakeup source caused the device to exit the hibernate mode. After the bit in the RTC Keep Alive
Register (RTC_KAR) is cleared that caused the device to exit the hibernate mode, then next external
wakeup source to assert is recognized and then all further wakeup sources is inhibited until the current
wakeup source is negated and its associated status bit is cleared. Recall that the WU_SRC_x bits are sticky
bits and do not return to a logic 0 until a logic 1 is written to their respective bit position in the RTC Keep
Alive Register (RTC_KAR).
