Communication interfaces
3.9.6.2 UART wakeup
The UART can be configured to generate an interrupt/wakeup on the first active edge that
it receives.
3.9.6.3 UART interrupts
The UART has multiple sources of interrupt requests. However, some of these sources
are OR'd together to generate a single interrupt request. See below for the mapping of the
individual interrupt sources to the interrupt request:
The status interrupt combines the following interrupt sources:
Source
Transmit data
empty
Transmit complete
Idle line
Receive data full
LIN break detect
RxD pin active
edge
Initial character
detect
