Wake-up requests LLWU wake-up sources
3.3.4.1 Wake-up Sources
This chip uses the following internal peripheral and external pin inputs as wakeup
sources to the LLWU module:
• LLWU_P0-15 are external pin inputs. See the chip's signal multiplexing table for the
individual input signal options.
• LLWU_M0IF-M7IF are connections to the internal peripheral interrupt flags.
NOTE
RESET is also a wakeup source, depending on the bit setting in
the LLWU_CS register. On devices where RESET is not a
dedicated pin, it must also be enabled in the explicit port mux
control.
