Synchronous Asynchronous
Receiver (EUSART)
9.1 16-Bit High-Speed Asynchronous Mode
The EUSART provides unexpected operation
when the 16-Bit High-Speed Asynchronous mode
is selected and the Baud Rate Generator Data
register values are loaded with zero (0). We do not
recommend using this configuration for EUSART
communication. The configuration is shown below
in the following table:
Work around
Ensure that the SPBRGH or the SPBRGL register
is loaded with a non-zero value.
