| The purpose of this test is to validate basic UART driver functions, | ||
| that are not tested elsewhere. | ||
| UART interrupt mode is used for the tests purpose. | ||
|
|
||
| Hardware setup required for these tests: | ||
| For single uart conviguration - UART0 TX connected to RX and CTS to RTS | ||
| For dual uart configuratiom - UART0 and UART1 TXs and RXs cross-connected | ||
|
|
||
| These test cases cover: | ||
| - UART configuration, | ||
| - UART error check, | ||
| - UART callback setup, | ||
| - Dual UART transmission with matched and mismatched configurations |
