13.1.2
The Wake-Up Enable (WKENA) register is a word-wide
read/write register that individually enables or disables
wake-up events from the MIWU channels. The WKENA reg-
ister is cleared upon reset, which disables all wake-up/inter-
rupt channels. The register format is shown below.

13.1.3
The WKIENA register is a word-wide read/write register that
enables and disables interrupts from the MIWU channels.
The register format is shown below.

The WKICTL1 register is a word-wide read/write register
that selects the interrupt request signal for the associated
MIWU channels WUI7:0. At reset, the WKICTL1 register is
cleared, which selects MIWU Interrupt Request 0 for all
eight channels. The register format is shown below.

Wake-Up Interrupt Control Register 1
(WKICTL1)
The Wake-Up Interrupt Request Select fields
select which of the four MIWU interrupt re-
quests are activated for the corresponding
channel.
00 – Selects MIWU interrupt request 0.
01 – Selects MIWU interrupt request 1.
10 – Selects MIWU interrupt request 2.
11 – Selects MIWU interrupt request 3.
