Question:
Is it necessary to use the CLK output of S6BT112A to adjust the baud rate in slave node?

Answer:

No, it is not necessary to use the CLK output of S6BT112A to adjust the baud rate in slave node.

The MCU can detect the baud rate of the CXPI communication bus by the CLK output of S6BT112A in slave node. However, if the MCU in the slave node has already been set the same baud rate with the master node, it is not necessary to use the CLK output of S6BT112A to adjust the baud rate in slave node. In that case, the CLK pin of S6BT112A in slave node can be left unconnected to the MCU. We recommend connecting the CLK pin to GND; no pull up/down resistor is needed.
