* Use this setting for synchronous or other
asynchronous protocols.
The transmitter will be active from the
startbit to 10 bit-times after the last high
databit (see example below). The speed
shall be set to ≅ 10 times the required
communication speed.
Example 19 200 bit/s
Start bit Data rate 19 200
1 bit = 52µs
Transmitter active 10x52µs = 520µs
Set the speed to 187.5 kbit/s
