register and do a logical OR with the register value. Instead,
just write the mask directly to the register address.
The register format is shown below.

To set up and use the Multi-Input Wake-Up function, use the
following procedure. Performing the steps in the order shown
will prevent false triggering of a wake-up condition. This
same procedure should be used following a reset because
the wake-up inputs are left floating, resulting in unknown data
on the input pins.
1. Clear the WKENA register to disable the wake-up chan-
nels.
2. If the input originates from an I/O port (the usual case),
set the corresponding bit in the port direction register to
configure the I/O pin to operate as an input.
3. Write the WKEDG register to select the desired type of
edge sensitivity (clear to 0 for rising edge, set to 1 for fall-
ing edge).
4. Set all bits in the WKPCL register to clear any pending
bits in the WKPND register.
5. Set up the WKICTL1 and WKICTL2 registers to define
the interrupt request signal used for each channel.
6. Set the bits in the WKENA register corresponding to the
wake-up channels to be activated.
To change the edge sensitivity of a wake-up channel, use the
following procedure. Performing the steps in the order shown
will prevent false triggering of a wake-up/interrupt condition.
1. Clear the WKENA bit associated with the input to be re-
programmed.
2. Write the new value to the corresponding bit position in
the WKEDG register to reprogram the edge sensitivity of
the input.
3. Set the corresponding bit in the WKPCL register to clear
the pending bit in the WKPND register.
4. Set the same WKENA bit to re-enable the wake-up func-
tion.
