**Related Modules:**

[UART](UART.md)

**Description:**

Defines basic attributes of the UART port. 

You can configure the attributes via  [UartSetAttribute](UART.md#ga76281a15464395451fc9844e717e0e10). If the parameters are not set, default attributes are used.

Attention
:   The UART controller determines which UART attribute parameters are supported.

**Since:**
