Error Detection
The WCOL bit in the SBCR register is provided to indi-
cate errors during data transfer. The bit is set by the Se-
rial Interface but must be cleared by the application
program. This bit indicates a data collision has occurred
which happens if a write to the SBDR register takes
place during a data transfer operation and will prevent
the write operation from continuing. The bit will be set
high by the Serial Interface but has to be cleared by the
user application program. The overall function of the
WCOL bit can be disabled or enabled by a configuration
option.

Programming Considerations
When the device is placed into the Power Down Mode
note that data reception and transmission will continue.
The TRF bit is used to generate an interrupt when the
data has been transferred or received.
