Check Error:
When a check bit error is detected during the decoding, a red 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 is an odd number (1) of 1 in the 8 bits data 00100000 and the
check bit should be 0. The check bit detected on the TX is 1, thus a check error
occurs.
After the decoder is set to none check, the decoding shows no error.
(00100000，LSB)
The check bit detected is 1
