During Sleep mode, all clocks to the EUSART are
suspended. Because of this, the BRG is inactive and a
proper byte reception cannot be performed. The
auto-wake-up feature allows the controller to wake-up
due to activity on the RXx/DTx line while the EUSART
is operating in Asynchronous mode.
The auto-wake-up feature is enabled by setting the
WUE bit (BAUDCONx<1>). Once set, the typical
receive sequence on RXx/DTx is disabled and the

EUSART remains in an Idle state, monitoring for a
wake-up event independent of the CPU mode. A
wake-up event consists of a high-to-low transition on
the RXx/DTx line. (This coincides with the start of a
Sync Break or a Wake-up Signal character for the LIN
protocol.)
Following a wake-up event, the module generates an
RCxIF interrupt. The interrupt is generated synchro-
nously to the Q clocks in normal operating modes
(Figure 19-8) and asynchronously if the device is in
Sleep mode (Figure 19-9). The interrupt condition is
cleared by reading the RCREGx register.
