SL6087 default UART

Hello together, I’m using the SL6087 with a microcontroller host, unfortunately the documentation is confusing to me, which UART is the default UART, I’ve found different comments inside the documentation, how is selected between the UARTs.

Thanks in advance!


Please refer to PTS doc

No doubt UART1 is the main and default UART, may I ask which doc and section that confused you?
