Low-Leakage Wakeup Unit (LLWU)
11.1 Reserved Bits in LLWU_PE3 and LLWU_F2 Registers
The LLWU_PE3[5:2] and LLWU_F2[2:1] bits are reserved on this device.
11.2 Introduction
NOTE
For the chip-specific implementation details of this module's
instances, see the chip configuration information.
The LLWU module allows the user to select up to 16 external pins and up to 8 internal
modules as interrupt wake-up sources from low-leakage power modes.
The input sources are described in the device's chip configuration details. Each of the
available wake-up sources can be individually enabled.
The RESET pin is an additional source for triggering an exit from low-leakage power
modes, and causes the MCU to exit both LLS and VLLS through a reset flow.
The LLWU module also includes two optional digital pin filters for the external wakeup
pins.
See AN4503: Power Management for Kinetis MCUs for further details on using the
LLWU.
