Silicon Labs EFM32: Can UART be used for wake trigger from EM2?
EFx32
A trigger to wake up from EM2 is introduced in another topic, but UART does not work with EM2, so it cannot be used as a wakeup trigger.
However, a Low Energy UART (LEUART) may be available as an alternative. LEUART is limited to a baud rate of 9600bps, but works with EM2 and can also be used as a wakeup trigger.
