IOT2050 Advanced serial port configuration

[applea9]

Hi bergmanu,

In the example, terminate resistor is turned on and setup / hold time is configured to 0x0005 for the IOT2050 Advanced serial port configuration. I have several questions regarding the configuration.

1. Normaly when the communication distance is long, we need to turn on the terminate resistor in the start and end device. But in the example, is it necessary to turn on the terminate resistor? and do we need to turn on the terminate resistor both in the IOT2050 side and end device side?

2. The default value for setup / hold time is 0xaa, why do we configure it to 0x0005, do we have any document about the configuration?

Thanks for you reply.
