Description
Wake-up enable register
The UART wake-up enable register is used to mask and unmask a UART event that subsequently notifies the
system. An event is any activity in the logic that can cause an interrupt and/ or an activity that requires the
system to wake up. Even if wakeup is disabled for certain events, if these events are also an interrupt to the
UART, the UART still registers the interrupt as such.
