LINSCI wrong break duration
SCI mode
A single break character is sent by setting and resetting the SBK bit in the SCICR2 register.
In some cases, the break character may have a longer duration than expected:
●
●
In the same way, as long as the SBK bit is set, break characters are sent to the TDO pin.
This may lead to generate one break more than expected.
