The Wake-Up Interrupt Enable bits control whether MIWU channels generate interrupts. The
WKIEN15:0 bits correspond to the WUI15:0 channels, respectively.
0 – Interrupt disabled.
1 – Interrupt enabled.
13.1.6 Wake-Up 1 Interrupt Enable Register (WK1IENA)
The WK1IENA register is a word-wide read/write register that enables and disables interrupts from the
MIWU channels. The register format is shown below.

13.1.7 Wake-Up Interrupt Control Register 1 (WK0ICTL1)
The WK0ICTL1 register is a word-wide read/write register that selects the interrupt request signal for the
associated MIWU channels WUI7:0. At reset, the WK0ICTL1 register is cleared, which selects MIWU
Interrupt Request 0 for all eight channels. The register format is shown below.

The Wake-Up Interrupt Request Select fields select which of the four MIWU interrupt
requests 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.
13.1.8 Wake-Up 1 Interrupt Control Register 1 (WK1ICTL1)
The WK1ICTL1 register is a word-wide read/write register that selects the interrupt request signal for the
associated MIWU channels WUI23:16. At reset, the WK1ICTL1 register is cleared, which selects MIWU
Interrupt Request 4 for all eight channels. The register format is shown below.
