Shifter Error Flags

The shifter error flag is set when one of the following events occurs:

For SMOD=Receive, indicates Shifter was ready to store new data into SHIFTBUF before the previous

data was read from SHIFTBUF (SHIFTBUF Overrun), or indicates that the received start or stop bit does

not match the expected value.

For SMOD=Transmit, indicates Shifter was ready to load new data from SHIFTBUF before new data had

been written into SHIFTBUF (SHIFTBUF Underrun).

For SMOD=Match Store, indicates a match event occured before the previous match data was read from

SHIFTBUF (SHIFTBUF Overrun).

For SMOD=Match Continuous, the error flag is set when a match has occured between SHIFTBUF and

Can be cleared by writing logic one to the flag. For SMOD=Match Continuous, can also be cleared when

the SHIFTBUF register is read.
