Frame Status, STS
The frame status can be one of the following:
Value Symbolic name Description
0x00 STSOK Good status
0x01 STSCRC CRC error
0x02 STSNOISE Noise error
0x04 STSABORT Status abort, frame did not complete
0x80 STSOVERUN Overrun error, frame did not terminate
properly
Since multiple bits may be set in STS, mask STS with the bit you wish to examine before
you make any comparisons.
Example: The following equation selects frames with CRC errors.
showonly
(STS & STSCRC = STSCRC)
#
Example: The following equation selects all frames with errors.
showonly
STS <> 0
#
Frame Length, Len
The frame length includes the three byte header but does not include the CRC bytes.
Example: The following equation selects frames with only a header.
showonly
Len <= 3
#
Frame Destination, Dst
The first byte of the frame is the destination.
