5.24.2.44 UART_WER Register

24.2.44.1 UART_WER Register (Offset = 5Ch) [reset = FFh]

The UART wakeup enable register is used to mask and unmask a UART event that would subsequently notify the system. The events are any activity in the logic that could cause an interrupt and/ or an activity that would require the system to wakeup. It should be noted that even if the wakeup is disabled for certain events, if these events are also an interrupt to the UART, then the UART will still register the interrupt as such.
