communication. The AnalogTestReg was set to CDh.
Remark: At 106 kbit/s, RxActive is HIGH during databits, parity and CRC reception.
Startbits are not included.
At 106 kbit/s, TxActive is HIGH during startbits, databits, parity and CRC
transmission.
At 212, 424 and 848 kbit/s, RxActive is HIGH during datbits and CRC reseption.
Startbits are not included.
At 212, 424 and 848 kbit/s, TxActive is HIGH during databits and CRC
transmission.
