10. The Error Expression during Decoding
End Frame Error:
Errors generated when the end frame condition is not met. When the stop bit is
set to 1, “?” error mark will be displayed if the stop bit is less than 1.
Check Error:
When check bit error is detected during the decoding, “?” error mark will be
displayed. For example, when the transmitting terminal is set to none check and
the decoder is set to odd check, the following check error occurs.
Wherein, there are odd number (1) of 1 in the 5-bit data 10111 and the check
bit should be 1; but the check bit detected on the TX is 0, thus check error
occurs.
Note that two error marks will be displayed when end frame error and check
error are detected at the same time.
The check bit detected is 0
The stop bit is less then 1
(10111，LSB)
