12.1.1
The KBI features include:
12.1.2
This section defines the KBI operation in wait, stop, and background debug modes.
12.1.2.1
The KBI continues to operate in wait mode if enabled before executing the WAIT instruction. Therefore,
an enabled KBI pin (KBPEx = 1) can be used to bring the MCU out of wait mode if the KBI interrupt is
enabled (KBIE = 1).
12.1.2.2
The KBI operates asynchronously in stop3 mode if enabled before executing the STOP instruction.
Therefore, an enabled KBI pin (KBPEx = 1) can be used to bring the MCU out of stop3 mode if the KBI
interrupt is enabled (KBIE = 1).
During either stop1 or stop2 mode, the KBI is disabled. In some systems, the pins associated with the KBI
may be sources of wakeup from stop1 or stop2, see the stop modes section in the
chapter. Upon wake-up from stop1 or stop2 mode, the KBI module will be in the reset state.
12.1.2.3
When the microcontroller is in active background mode, the KBI will continue to operate normally.

Up to eight keyboard interrupt pins with individual pin enable bits.
Each keyboard interrupt pin is programmable as falling edge (or rising edge) only, or both falling
edge and low level (or both rising edge and high level) interrupt sensitivity.
One software enabled keyboard interrupt.
Exit from low-power modes.
