Figure 11-11. Missed Read of Overflow Condition
In this case, an overflow can easily be missed. Since no more SPRF interrupts can be generated
until this OVRF is serviced, it is not obvious data is being lost as more transmissions are
completed. To prevent this loss, either enable the OVRF interrupt or take another read of the
SPSCR following the read of the SPDRR. This ensures the OVRF was not set before the SPRF
was cleared. Future transmissions can set the SPRF bit. Figure 11-11 illustrates the described
process. Generally, to avoid a second SPSCR read, enable the OVRF to the core by setting the
ERRIE bit.
