47.5 Reset
All registers reset to a particular value are indicated in Memory map and registers.
47.6 System level interrupt sources
There are several interrupt signals that are sent from the UART. The following table lists
the interrupt sources generated by the UART. The local enables for the UART interrupt
sources are described in this table. Details regarding the individual operation of each
interrupt are contained under various sub-sections of Memory map and registers.
However, RXEDGIF description also outlines additional details regarding the RXEDGIF
interrupt because of its complexity of operation. Any of the UART interrupt requests
listed in the table can be used to bring the CPU out of Wait mode.
