13.1.1
The WK0EDG register is a word-wide read/write register
that controls the edge sensitivity of the MIWU channels. The
WK0EDG register is cleared upon reset, which configures
all channels to be triggered on rising edges. The register for-
mat is shown below.
WKED
13.1.2
The WK1EDG register is a word-wide read/write register
that controls the edge sensitivity of the MIWU channels. The
WK1EDG register is cleared upon reset, which configures
all channels to be triggered on rising edges. The register for-
mat is shown below.

13.1.3
The WK0ENA register is a word-wide read/write register
that individually enables or disables wake-up events from
the MIWU channels. The WK0ENA register is cleared upon
reset, which disables all wake-up/interrupt channels. The
register format is shown below.
