21.7 Power-Saving Modes

The UART provides support in power-saving modes, including the capability to run in Sleep and Idle modes. If a transmission or reception is in progress, and a power save command is executed, the operation will abort. SFR data, including UxCON, UxSTAT, UxBRG and the RX and TX buffers, will retain their values upon a wake condition and do not need to be reinitialized.
