Low-Leakage Wakeup Unit (LLWU)
19.1 Chip-specific LLWU information
This chip uses the following internal peripheral and external pin inputs as wakeup
sources to the LLWU module:
• LLWU_P0-P16, P19-P21 are external pin inputs. Any digital function multiplexed
on the pin can be selected as the wakeup source. See the chip's signal multiplexing
table for the digital signal options.
• LLWU_M0IF-M7IF are connections to the internal peripheral interrupt flags.
RESET is also a wakeup source, in addition to LLWU pins, and
can be diagnosed by reading the System Reset Status Registers
within the RCM.
