WAKE-UP INTERRUPT CONTROL
REGISTER 1 (WKCTL1)
The Wake-Up Interrupt Control Register 1 (WKICTL1) regis-
ter is a word-wide read/write register that selects the interrupt
request signal for the associated channels WUI0 to WUI7.
Upon reset, WKICTL1 is set to 0, which selects MIWU Inter-
rupt Request 0 for all eight channels. The register format is
shown below.
WKINTR0:7 Wake-Up Interrupt Request Select. Each field
selects which of the following four interrupt re-
quests outputs to the ICU31L are to be activat-
ed for the corresponding channel.

WAKE-UP INTERRUPT CONTROL
REGISTER 1 (WKCTL2)
The Wake-Up Interrupt Control Register 2 (WKICTL2) regis-
ter is a word-wide read/write register that selects the interrupt
request signal for the associated channels WUI8 to WUI15.
Upon reset, WKICTL2 is set to 0, which selects MIWU Inter-
rupt Request 0 for all eight channels. The register format is
shown below.
WKINTR8:5 Wake-Up Interrupt Request Select. Each field
selects which of the following four interrupt re-
quests outputs to the ICU31L are to be activat-
ed for the corresponding channel.

13.5
The Wake-Up Pending (WKPND) register is a word-wide
read/write register in which the Multi-Input Wake-Up module
latches any detected trigger conditions. Register bits 0
through 15 serve as latches for channels WUI0 through
WUI15, respectively. A bit cleared to 0 indicates that no trig-
ger condition has occurred. A bit set to 1 indicates that a trig-
ger condition has occurred and is pending on the
corresponding channel. This register is cleared upon reset.
The CPU can only write a 1 to any bit position in this register.
If the CPU attempts to write a 0, it has no effect on that bit.
To clear a bit in this register, the CPU must use the WKPCL
register (described below). This implementation prevents a
potential hardware-software conflict during a read-modify-
write operation on the WKPND register.
The register format is shown below.

13.6
WAKE-UP PENDING CLEAR REGISTER
(WKPCL)
The Wake-Up Pending Clear (WKPCL) register is a word-
wide write-only register that lets the CPU clear bits in the WK-
PND register. Writing a 1 to a bit position in the WKPCL reg-
ister clears the corresponding bit in the WKPND register.
Writing a 0 leaves the corresponding bit in the WKPND reg-
ister unchanged.
Reading this register location returns unknown data. There-
fore, do not use a read-modify-write sequence to set the in-
dividual bits. In other words, do not attempt to read the
